Updates from New Zealand
Where applicable, this section will be updated to include new information as our friendly NZ “beta testers” experience CD before anyone else in the world. On Community Days with new, unpredictable features, the only way to know for sure how they’ll function is having others experience it first. Check back here before CD to see if there’s any last-minute tips you need to know!
Playing in NZ? Thanks! We monitor reports on The Silph Road carefully, though you can also submit reports here on GamePress or directly to NoLucksGiven on twitter. Additionally, it is even more recommended you have a stable internet connection and consider doing a test evolve, as Niantic acknowledges server issues can and do happen (especially in your region) during CD, yet refuses to compensate/correct this known issue.
Guaranteed Sinnoh Stones from Go Battle League is currently reported as not working in NZ. Stay tuned. Sinnoh Stones through GBL are now live.
Rhydon and Rhyhorn are now closer, making it easier to hit Great throws.
Where to Play
Rhyhorn spawns will be dramatically increased everywhere during the duration of this event. You aren’t required to play anywhere specifically, but here are some tips for getting the most out of the location you choose.
Since this event is 11AM-2PM based on local time, By playing near a timezone shift, players in some parts of the world can take advantage by starting an hour earlier or ending an hour later. Start East then make your way West sometime after the first hour. This shouldn’t affect most players but can be a nice bonus to players willing to travel a little more during CD. Remember to stay West as you evolve for the exclusive move.
This note is now also applies to several countries in South America and Africa that exist in two hemispheres. If you’re near the divide, let us know how those mechanics work! It's very possible that you can essentially double your Community Day hours.
Exploring the Community
Use Community Day, and Pokemon Go in general, as an excuse to explore local areas. If you’re blessed with multiple, good locations, make use of them throughout various Community Days!
Playing with Friends
Community Day should be about the community, both the area and your local PoGo Players. Get together with friends, find your local group using PokeNav, or be the first in your area to create a group. If you see other trainers in your gyms, that means there’s others out there playing! More trainers means more fun, and Lure Modules appear for all players, so you can all share the increased spawns. Returning and new players- ask around and figure out where established players are planning to play!
Gyms for Raids
Playing near gyms may lead to easy raid completion before or after the event, while everyone is already out playing. During many CDs you may not want to break to Raid, but playing near gyms still allows you to raid immediately following the event, should any eggs spawn for you.
Clusters and/or Lures
If you want to catch the most Rhyhorn, focus on cluster spawns in areas with lots of network traffic such as parking lots and apartment complexes.
Pokestop dense areas that can be easily Lured up are another go-to. After the spawn shakeup from a few months ago, many players have turned back to playing in areas with as many Pokestops as possible.
Pursuing weather-boosted Rhyhorn will grant you higher CP Rhyhorn so it’s advised to hunt in forecasted Clear or Partly Cloudy areas. This comes with it decreased catch rates but is offset in Stardust gained and saved from catching weather boosted Pokemon. Pay attention to official weather reports as well as other trainers playing in different level 11 S2 cells (in-game weather boundaries).
Weather boosted Pokemon have an IV floor of 4/4/4. This means their IV spreads are more likely to be better for PvE, but likely impossible to have ideal IV for PvP.
Every Community Day is Different
From February to July of 2019, nesting spawns stopped or are at least extremely dulled during CD hours. Every Community Day is slightly different in regards to spawn rates but it is worth noting that players can likely visit nests and not worry about diluted Rhyhorn spawns.
During Ralts Community Day, a forced nest shift occurred, causing many nests to be overrun in some regions with Poocheyena, Bulbasaur, or other spawns. This was fixed before the end of CD, but it’s a good reminder that every Community Day is different and presents a new opportunity for new/returning bugs. This guide covers what you can reasonably expect, but having backup plans is always smart!
Rhyhorn is currently unavailable in research, eggs, and Rocket Grunt battles. It is a nesting species, and a 3km Buddy Pokemon.
Rhydon can currently be encountered in 4* Raids. These can't be shiny, even if acquired during CD hours.
Any previous Rhyhorn/Rhydon obtained with undesirable IVs should be traded at least for candy and to reroll IVs, preferably with a Best Friend. Using a Lucky Trade is also a good idea for players with limited CD time. Additional Rhyhorn candy can be earned prior to the event by making Rhyhorn your Buddy Pokemon, and by making Rhyhorn a Gym Defender and stuffing it full of berries! If you have limited time to play this CD and are close to the candy needed for another evolution, these tips can put you over the threshold for evolving another Rhyhorn for the exclusive moveset.
Acquiring Sinnoh Stones
Sinnoh Stones are required to evolve Rhydon to Rhyperior. If you’re running low, or just want to evolve a bunch of the Drill Pokemon, there’s a few ways to acquire them still before Community Day starts.
Research Breakthroughs- Collecting your 7th research stamp and claiming the breakthrough can occasionally reward a Sinnoh Stone.
Daily PvP Rewards- 4 PvP rewards can be obtained each day, 3 from battling another trainer and 1 from training against a team leader. Each of these 4 battles has a chance to reward a Sinnoh Stone.
Go Battle League- Wins in GBL can reward Sinnoh Stones as a mystery item. On Community Day, completed sets guarantee 2 Sinnoh Stones on Community Day. Because of this, it’s advisable to bank 2 GBL sets (6km) for Saturday and claim them before Community Day. After all of your Community Day walking you may have unlocked some more. Players are limited to 5 sets (10 Stones) per day.
Items to Bring
6 Star Piece
TRIPLE STARDUST is the best time to crack open a Star Piece and on Community Day that Star Piece goes even farther.
Having 6 Incense will let you crack open one every 30 minutes and make it last the entirety of the event. How many Incense you choose to use depends on availability, meta-relevancy, and rarity of the featured Pokemon. 25 Incense can be purchased in bulk for 1250 in the Shop (50 each) at any time for those looking at an alternative to various Legacy Special Boxes. 25 Incense is enough for 4 Community Days and an extra to spare.
Keep walking! Incense spawns more Pokémon while you’re moving! Even if you’re stuck at work where nothing spawns during the event window, popping some Incense could help you nab a shiny or two. Remember that “quick catching” your Incense spawns will still make them visible on the map after the catch.
Lure modules placed during Community Day hours will last 3-hours long. Playing in an area with a lot of stops will allow you access to a lot more spawns too.
This Silph Road study concludes that the new specialized Glacial, Mossy, and Magnetic lures double the amount of lured spawns, with half of the spawns coming from a specific list and half coming from the biome, which should be taken over during Community Day. Because of this, using a new, upgraded Lure Module quickly becomes worthwhile, during CD’s 3-hour lure bonus.
These lures can bring rarer catches including some evolved forms with bonus Stardust, but you may want to still focus on the feature Pokemon spawns with their limited window exclusive moveset and increased shiny chance.
If you don’t plan on purchasing Glacial, Mossy, and Magnetic lures yourself, it may be smart to plan for when you do run into them. Select and rename desired Eevee, Nosepass, and Magneton so that you don’t detract from your time playing during Community Day to fumble through your Pokemon Collection.
PRO-TIP: Use a new Lure right before CD ends. It will still last 3 hours and you can catch a few Pokemon while you evolve and trade Rhyhorn. You won’t be able to lure anything Lured during Community Day, but there's usually a few unlured Pokestops, hopefully ones in air conditioning or with comfortable seating. This may not be possible in urban and extreme rural playing without a lot of communication.
0-1 Lucky Eggs
Community Day can be a great time to coordinate Friendship level ups for both players to egg and receive double XP as it’s likely you’ll both be playing. Make sure to coordinate with your friends as it is usually easier to plan for level ups in the minutes before Community Day starts so that the actual event can be spent catching.
Berries and Great/Ultra Balls
These tips may be even more relevant this Community Day which immediately follows the Stardust Blast event.
It’s always a good idea to stock up before CD. The themed research “Catch 3 Rhyhorn” can be easily accomplished to help keep the Pokeballs flowing during the event. So it may not be necessary to stock up beforehand in all areas. Active Pokemon from Lures and Incense can also deplete your resources. Players low on resources should remember to always open 20 daily gifts and to upgrade item bag storage as soon as possible. It is an investment that quickly pays for itself, especially if you’re able to occasionally grind and stock up on items.
One of the best uses in the game for paid Incubators is Community Day events featuring 10km hatchable Pokemon. During Ralts, Larvitar, and possibly Beldum CD, the featured Pokemon was obtainable via eggs at an increased rate. For Ralts CD, 100% of eggs acquired contained Ralts (Note: Egg contents are determined when the eggs enter your inventory, though the shiny rate is only increased if hatched during Community Day). Because of this, saving incubators to use for future Community Days featuring rare Pokemon is extremely advisable.
While it is unknown what percentage of eggs will hatch Rhyhorn, this may be a feature worth taking advantage of, based on your personal preferences.
Rhyhorn is largely considered meta relevant, meaning some players may choose to incubate this CD.
Because you may already be running Star Piece, Incubating a few extra eggs may be worthwhile.
Breaking the Bank
The Research “Bank” or “stack” aka queue is a feature that is officially not supported by Niantic. This means proceed with caution. Niantic’s official stance is that they will not in any way compensate for any errors that arise from using this feature. That all said, it can be very helpful on CDs offering bonus Stardust.
When you run from a research encounter (or an error occurs or your collection is full), the encounter is stored above your existing research tasks. This gives the appearance of having 4 research tasks.
Fleeing from additional tasks (simply claim your reward then run away from the encounter) will allow you to store multiple encounters this way. This is what is commonly referred to as the “bank” “stack” or “queue”. The research will appear here from oldest to newest, meaning if you accidentally run from an encounter, you will have to clear through your entire bank to find it again. Rewards will appear in the order that you complete the task, with only one visible at a time. They’re not gone. Even though you can only see one at a time, the other research is “underneath” the top encounter in your stack. Catch that Pokemon and the next will be visible. While you can store breakthrough encounters and Special research encounters, these follow different rules and do not appear in the same bank.
What’s the Catch?
There is a limit of 100 banked Pokemon. When exceeding this limit, Pokemon will be deleted from the bank. This is the part Niantic now claims no responsibility for. Bank carefully. If you’re going to make use of this feature, consider downloading a counting widget to track your capacity. Recent reports have the oldest banked Pokemon being deleted (though it's always possible this can change). It’s a good idea to know the first Pokemon you have banked and check to see if that changes after acquiring more rewards. If so, you’re at capacity and should catch a few before completing more research.
Using the bank can be a very rewarding element to quickly completing research tasks. After becoming familiar with throwing at task rewards, banking them will allow you to quickly encounter Pokemon that are easy to throw at. The Research Task List can give you a full list of currently available task rewards.
Even if you currently have 0 banked research encounter rewards, start saving today!
Star Piece Like a Beast
You’ll want to make room in your Pokemon Storage if you haven’t already. Delete room for Turtwig so you can IV check them after. Clear 100 slots for your banked encounters (which may also have good IV) and clean even more space for wild encounters. You’ll want as much room as possible going into CD and you’ll want to make sure you spend as little time switching menus as possible so that you can catch anything that pops up. Even common spawns during this even grant as much dust as you’d normally receive for a Stage 1 Pokemon on a Star Piece.
1st catch of the day or 7th streak catch of the day is additional bonuses added to the dust value based on evolution stage.
If you will catch around 21 Pokemon before Community Day, it is more beneficial to not bother having your 1st catch of the day occur during CD. This counts after midnight the night before too. Most players shouldn’t aim to capitalize on this bonus- but if you really only play during CD, this is fine to do. Put simply, just play the game and don’t worry about this niche min-maxing.
However, players with their 7-day streak on Sunday will benefit from waiting if they wouldn’t otherwise earn 13,200 Stardust in the meantime. Accounting for weather boosted and evolved spawns this number is probably closer to 115 spawns. Basically, if you’re planning on playing the morning before CD, you can do so as normal or you can not play and basically receive the same amount of Stardust or more!
Before Community Day Starts
Here are a few other things to keep in mind right before Community Day starts for making the most of the granted bonuses.
If Community Day is about to start, wait to Incubate your eggs. starting them during CD will give you the 1/4 distance.
If coordinating Lucky Egg friendships, encourage your friends to egg and advance friendships before the event starts. This allows you to focus on catching once Rhyhorn start spawning!
Feed your buddy. Community Day lasts 3 hours, the exact amount of time that your buddy will be content after feeding. Fill up your Buddy’s stomache for a few extra hearts while walking during CD.
Existing spawns can change to Rhyhorn. Clicking on Pokemon to catch or even just to shiny check will prevent them from turning into Rhyhorn. It’s fine though to check for shinies you don’t yet have. If you want to catch the most Rhyhorn, avoid clicking on spawns as Community Day is about to begin. Catch them for triple dust instead!
You can only complete research from each stop once daily. If you complete a task at a given stop, you cannot receive the “Catch 3” task from that stop during Community Day. Occasionally, receiving the task from a stop will lock it into its non-CD task.
Now, with those in mind, there is still room for choice. If you’ll be playing all Community Day then you might not care about one spawn point here and there, and catching weather boosted Machop or shiny checking a Wailmer may be worth it to you. Likewise, you may not find it necessary to fill your inventory with Community Day eggs.
Use this time before the event starts to prep; spin stops, transfer Pokemon, open gifts (and level up friendships), Raid, check-in, and obtain/give out Meltan boxes.
Your mileage may vary with using this feature, but Pokemon Go Community Days often come with a lot of walking. Getting your Buddy excited before Community Day can allow you to accumulate even more buddy candy.
Set Alarms for Items and Evolving
Before the event, consider setting an alarm on your phone for various CD intervals to remind yourself to reapply premium items if you’re using them. There’s a lot to keep track of during Community Day between quick catching, shiny checking, appraising, and talking and catching up with friends! Setting some alerts the night before could potentially earn you thousands of Stardust you’d lose out on if you forgot to break a Star Piece.
With 11:00AM Community Days, a wake up alarm doesn’t hurt either!
During Community Day, Research Tasks are changed to “Catch 3 Rhyhorn” with the following rewards;
2 Ultra Balls
5 Great Balls
2 Pinap Berries
1 Golden Razzberry
Rhyhorn encounter (CP range 426-460)
This allows you to not stress about Research during the event and concentrate on catching. It also means that Trainers can rest easy knowing that Community Day itself will help provide them with additional Pinaps, Ultra Balls, and Great Balls! There are a few additional things to keep in mind as far as how this functioned last Community Day;
Research from each stop can only be completed once each day. If you complete a task at a given stop, you cannot receive the “Catch 3 Rhyhorn” task from that stop.
Tasks revert to their pre-CD tasks when CD is over but you cannot receive research from Stops where you completed “Catch 3 Rhyhorn” or the original research.
Because of this, you may decide to skip over stops during CD that you know give desirable research (from Discord, Facebook, etc.) or complete them before CD starts.
Many players may do the opposite, choosing not to complete Research in areas they know they will be during CD for easy rewards.
Check to see if you have completed the Research Task of a given Pokestop by the indicator in the top right corner of a Pokestop
What's in the Box?
Legacy Community Day Special Boxes have held a variety of supplies and are available shortly before the start of Community Day. A list of previous and current contents can be found on our Legacy Special Box list (as well as cost analysis breakdowns). Some Community Days also feature Great and Ultra Boxes, which can be amazing deals for an extremely limited time, disappearing at the end of CD in America. This section will include a more thorough breakdown upon release of the Special Boxes in the Shop.
Expect 0-3 new boxes to be added during CD and removed shortly after.
Community Day Raids and Eggs and Rocket Grunts
Ralts and Turtwig Community Day introduced new ways to acquire high IV versions of the featured Pokemon during Community Day!
Updates to this section will appear in “Updates from New Zealand” at the start of the article, as Niantic and New Zealand reports offer us more information.
Rhyhorn raid should appear as normal Tier 1 Raids during Community day. This means the earliest they can hatch is 12:00 (northern hemisphere), and some will extend past Community Day. Other raids will still spawn normally.
Rhydon can currently be encountered in 2* Raids. These can't be shiny, even if acquired during CD hours. Both raids will likely coexist during CD hours.
Ralts hatched from every egg obtained during Community Day. The only non-Ralts eggs available were 7km gifted eggs (and those obtained prior to CD).
Turtwig certainly wasn’t in every egg. It was likely slightly boosted, like seen with Larvitar and Beldum, but specific rates are unknown.
There is limited data on this subject, but Rhyhorn likely won’t hatch from every CD obtained egg.
Rocket Grunt Battles
A few Community Days have been followed by the release of the featured Pokemon available as a Shadow Pokemon from Rocket Grunt battles. With Shadow Rhyhorn currently unreleased, it’s likely we will see it arrive after Rhyhorn Community Day.
During Turtwig CD, a majority of Rocket Grunt encounters rewarded Shadow Turtwig. While you’ll have to decide if these are worth pursuing for yourself, it can be a fun way to obtain high-IV Pokemon.
Turtwig Community Day was the first to have Shadow Turtwig released prior to its featured CD. There has yet to be a Shadow Pokemon launched on its respective CD, though this is certainly possible. Rhyhorn is still not encounterable from Rocket Battles. It is likely that future CD Pokemon may be introduced through Rocket Leader Battles following their Community Days.
Community Day has also been used as a time for Niantic to test/tease/experiment with new features. Shadow Rhyperior isn’t totally out of the question for a last-minute addition.
Exclusive Move Analysis : Rock Wrecker
Rock Wrecker makes a big impact, worthy of its own article. Read more about Rock Wrecker in this stand alone analysis on on Rhyperior’s Pokemon Page.
For PvP, don’t forget that Rhyhorn and Rhydon also have pretty high CPs, and some PvP utility.
Look for PvP-ready CPs
Finding Pokemon that can be evolved to be near the CP-cap in PvP leagues can save a lot of Stardust. Before evolving, consult a CP/IV calculator to confirm your Rhyhorn will stay below the CP thresholds. Looking for Rhyhorn with CP around or below these thresholds can be great for trainers interested in PvP with limited resources;
For Great League Rhyperior, look for Rhyhorn with CP 626-656 and below. Rhydon will have CP 1266-1274 in this range.
For Great League Rhydon, look for Rhyhorn with CP 740-774 and below.
For Ultra League Rhyperior, look for Rhyhorn with CP 1035-1097 and below. Rhydon will have CP 2106-2125 in this range.
For Ultra League Rhyperior, look for Rhyhorn with CP 1232-1294 and below.
If you’ve built friendship with a Rhyhorn/Rhydon, make sure to make that Pokemon your buddy before evolving.
Determine how many Rhydon you want to evolve this Community Day and plan accordingly as far as resources and acquiring high IV Rhyhorn goes. Set goals and pay attention to how much candy you earn. Keeping track can help you determine play patterns for future CDs.
As mentioned previously, especially if your CD availability is low, swap Rhyhorn with local players leading up to CD and make use of the Lucky friend feature if you're desperate and don’t want to wait till December to evolve them.
If you’re low on Sinnoh Stones, hop into Go Battle League and concede a few battles. Each set of 5 rewards 2 Sinnoh Stones on CD, limit 5 sets per day.
Set goals based on previous Community Days as a benchmark. Use this to let you know how aggressively you need to hunt and Pinap, as well as how many high IV options to target.
Each evolution costs 123 Rhyhorn candy which is 31 catches + transfers or 18 catches w/ Pinaps + transfers. Maxing out a Pokemon will cost between 118-304 candy depending on the level (248 for level 20 Pokemon). Evolving and Powering Up a full team (with average level 20) will cost 2227 candy. This can be accomplished with 382 Pinap catches + transfers or 557 catches + transfers. Adjust your goals to make the most out of your Rhyhorn candy. However, you only have to evolve them today, not power them up. You can continue to earn Rhyhorn candy after the event to Power Up evolved Rhyperior!
As noted in “Looking Forward” evolving extra Shiny Rhyhorn with the exclusive move may make great future trades with Lucky Friends.
You (probably) have until 1 hour after the event ends to IV check, trade, and evolve for the exclusive moveset. Set alarms and keep track of how long different activities take you so you can be better prepared for future CD events.
When picking a trading partner, there are now three different options to consider each with their own benefits.
Play Community Day with your trading partner.
Catch the same spawns (for even trades) and split the role of IV checking
Can start trading even before CD ends
Play 10km (6.21 mi) distance from your trading partner.
1 additional candy per trade.
Very possible this CD if you meet someone at an EX Raid, though Rhyhorn aren’t super useful.
Trade with a Lucky Friend!
Obviously, this will can a combination of one of the previous two options. Coordinating with a Lucky Friend during CD can allow you to swap a day 1 shiny Rhyhorn to reroll IVs. Coordinating with multiple Lucky friends can allow you to reroll a few for IVs, though you can only do one special trade each day.
Here are some additional features to keep in mind about trading:
Players are limited to 100 trades + 1 special trade per day. This is reset after your phone goes past midnight.
Swapping a Shiny will count as a Special Trade and can also be done once daily.
Pick a trade partner you have high friendship with. IV floor increases with friendship tier.
Good Friendship - 1/1/1 IV floor
Great Friendship - 2/2/2 IV floor
Ultra Friendship - 3/3/3 IV floor
Best Friendship - 5/5/5 IV floor
Pokemon caught farther than 10km (6.21 mi) apart award 2 candy when traded.
Lucky Pokemon have an IV floor of 12/12/12. Read more about Lucky Pokemon here
The Technicals: Catch Rate and IV Checking
Rhyhorn will likely have its Base Catch Rate changed to 40% as we have seen with previous CD spawns.
Similar to Swinub Community Day, Rhyhorn is a particularly difficult Pokemon to make Great throws on. Because of this, you may wish to use better balls more often.
Our easy-to-use catch rate calculator can be found here if you’d like to do your own calculations. Here are the breakdowns for players with a Gold Grass badge. These calculations also assume maximum radius Great! throws. Your ability to reliably throw into smaller bonus radiuses may also increase throughout the day, increasing your catch rate.
Rhyhorn levels 1-7 have an 89% chance or higher to be caught with a curved Poke Ball Great! Throw.
Rhyhorn level 12 and below have a 90% chance or higher to be caught with a curved Great Ball Great! Throw.
Rhyhorn level 20 and below have a 90% chance or higher to be caught with a curved Ultra Ball Great! Throw. Even a level 35 Rhyhorn has an 82% chance to be caught per throw using a curved Great! Throw Ultra Ball, allowing for proficient throwers to utilize Pinap berries every throw.
Throwing with no bonus will eat through your resources faster making it worthwhile to learn how to consistently throw Great! Throws (+ video link) The following will result in a 90% catch rate with curve balls and no throw bonus:
Poke Ball Rhyhorn levels 1-4
Great Ball Rhyhorn levels 8 and below
Ultra Ball Rhyhorn levels 13 and below
Ultra Ball Razz Berry Rhyhorn levels 25 and below. Great Ball Golden Razz Berries can be used on higher level Rhyhorn to ensure a 90% catch rate per throw.
Searching “4*” will display all perfect Pokemon. Searching “4*&Rhyhorn”, ”4*&328”, or “4*&+Rhyhorn” will display all perfect Rhyhorn. 4* and sorting by recent should also suffice. More tips on using the new appraisal system to its fullest can be found in the below section New Appraisal Tips.
Knowing how dust cost relates to Pokemon level can also help in quickly determining a Pokemon's level and IV. Here are the associated dust costs for the following levels;
35 - 8000
34/33 - 7000
32/31 - 6000
30/29 - 5000
28/27 - 4500
26/25 - 4000
These values can be used to determine high-level Pokemon at a quick glance.
New Appraisal Tips
Many Pokemon IVs can now be quickly viewed using the new visual IV system. It should be feasible to scan all Rhyhorn within the 1-hour timeframe to scan for optimal IVs. But what should you look for while IV scanning?
For PvE (and Master League PvP), you’ll want to sort by CP, search “3*” and save any with 15 Attack IV. Rename them in a way you can easily recognize without having to check again. Consult your set goals and Rhyhorn candy. If you need more with high IVs, consider repeating this process and looking for 14 Attack IV or searching “2*”. If you have more than your set goals, trim from the worst you’ve selected.
For PvP, optimal IV sets will almost all be 1* options. 2* will contain some ideal IVs as well though 1* will be better on average as that allows for 0 attack IV combinations. Scanning the search range "1*,2*" for low attack and high defense and stamina will allow you to look for ideal PvP IVs. Remember to look below the previously specified IV caps from the section “Look for PvP-ready CPs”. Consult with a CP calculator to verify the Pokemon will evolve under the cap. Some trainers may also chose to skip IV checking during this step or/and evolve shiny Pokemon. Evolve extra below CP caps for future trade fodder.
Then trade any Pokemon you haven’t marked as favorites. Leave yourself time to evolve at the end of this process. Searching “Traded” or sorting by new can allow you to easily view your new Pokemon. Compare these to your previously selected best options. Consider evolving any Lucky Pokemon for a huge dust discount. After evolving to satisfy your goals, evolve extra Rhyhorn with high CP, below PvP caps, or shiny for future trade fodder. Remember to save some candy if you wish to Power Up some Rhyperior!
When Rhyhorn’s Community Day is over, there are still plenty of opportunities to get good Rhyperior with the exclusive move through trading. Evolving extra Rhydon can be a great idea to attempt to trade with friends afterward for high IV rerolls.
Lucky Friendship is a total game-changer for exclusive movesets. Interacting with Best Friends can now create Lucky Friendships! This will make your next trade a guaranteed Lucky! One of the best uses for these trades will be shiny Pokemon, rare Pokemon, and Pokemon with exclusive legacy movesets. CD brings all three! For this reason, evolving extra shiny Rhyhorn gives you the perfect Lucky Trade fodder. Encourage your Best Friends to do the same.
Using up all your Rhyhorn candy on evolutions gives you an additional incentive to catch future Rhyhorn, which will then allow you to power them up and unlock additional moves. Rhyhorn in Raids and Rocket Grunt Battles will provide future Rhyhorn candy income to take advantage of. In addition, these options could provide high IV Rhyhorn to make use of.
It’s not too late to find some high IV Rhyhorn too. Whether it be Rhyhorn in your collection you didn’t notice/have the time to evolve during CD or new ones you catch, December is likely to have another CD weekend where exclusive moves become available again. If you don’t manage to find a good Rhyhorn worthy of your Stardust this weekend, evolve some anyways, attempt some lucky trades (on evolved and unevolved), keep looking, and evolve some in December! Note: This event is not confirmed for December, it's just what happened in 2018 and 2019.
