TL;DR: Should You Pull?
What Does It Do?
Defensive version of Phoebe and Dusknoir, with a stronger focus on supporting the team defensively in a similar fashion to Drake and Salamence. It is also one of the bulkiest units to be released. This puts it in great stead to be the team’s main tank, preferably supported by a backup healer (like SS Leaf). On teams with strikers that cannot maximize their own Attack and/or Special Attack, Blastoise becomes a useful asset thanks to Team Shout 9, which means it should be used primarily as the 1st slot in Team Tactics.
It is arguably best used in the Champion Arena, where it benefits from the rule of not being able to reuse a Sync Pair across different stages of a run. It can also operate well in Co-Op like Phoebe & Dusknoir, thanks to Party Crashers and abusing the switch mechanic. It should be noted that it lacks the redirection capabilities to truly shine in Co-Op.
However, there are much better options for general use like Skyla and Swanna. The Unovan Gym Leader offers similar boosts and has the ever-important Potion, so it is hard for Sygna Suit Blue to find a consistent placement against or ahead of the best free Support Sync Pair.
How Do I Use It? (Grid, Lucky Skills, And Comps):
This incomplete Sync Grid serves as a basic starting point for SS Blue, with Smart Cookie and Wise Entry 2 buffing its Special Defense in tandem with Force Field 4. Party Crashers ensure a first Critical Hit on all allied Sync Pairs, though this isn’t necessary for players pairing Blastoise with self-sufficient strikers. Endurance helps keep Blastoise alive to take one extra hit. There are Rain based boosts on the other end of the Sync Grid, but it isn’t really recommended considering Blastoise’s poor offensive stats.
Defense Crush 2 works well as a Lucky Skill if players intend to pair SS Blue with physical strikers like Kris or SS Grimsley. Kris particularly benefits from Team Shout 9 to maximize its Attack without having to spend precious points in Feraligatr’s Sync Grid. For a mono Water build, players could run Misty in the last slot, whose Evasiveness and Passive Healing support extend SS Blue’s longevity.
Is It Worth Pulling?
No. SS Blue is a decent Sync Pair, but in terms of Gem efficiency, he is definitely not a priority. Players who missed out on SS Red in his first offering would want to go for him first, or SS Leaf, who has less competition for a team slot. Considering the goddess that is Skyla and Swanna, SS Blue, unfortunately, receives the short end of the stick when released near simultaneously to his Kantonian rivals.
In repeat runs where he is not packaged with other top tier or better units, SS Blue may be a worthwhile investment as one of the game’s best dedicated main tanks.
