Overview

Dialga is no longer quite as great as it once was, especially when compared to its Origin Forme's use of Roar of Time. Still, it's not the worst Pokemon to raid for. Despite being a Dragon, Dialga's only weaknesses are Ground and Fighting, so the normal Dragon team can sit this one out. This can definitely be a difficult raid, but not too difficult, fortunately.

Note that the Duo is possible, but this guide focuses on the Trio.

Approach

Team composition

  • The two types in play this time are Ground and Fighting

    • Ground tends to take the lead by a pretty wide margin, especially when Primal Groudon is involved.

    • Fighting has solid performance overall that makes it worthwhile as well.

Dodging strategy

  • Dodging is extremely helpful vs Thunder and Draco Meteor in particular

  • Know when to dodge, and when to let a Pokemon faint. If your Pokemon won't survive the next Charged Move and is close to its own Charged Move, then dodge. If it's about to drop and likely won't generate enough energy to launch another Charged Move, then let it go.

Best Raid Boss Counters

Supreme Mega Evolution Counters

Primal Groudon Primal Groudon
Fast MoveCharge MoveRating

Nothing in the game comes close to Primal Groudon in this raid. It's the king of DPS and TDO alike, and its Primal boost turns a number of the top Ground Types nuclear, especially in Clear weather. Add to this a resistance to Dialga's Steel Type moves and a double-resistance to Thunder, and it should be very clear why Primal Groudon is unparalleled. 

Mega Blaziken Mega Blaziken
Fast MoveCharge MoveRating

Mega Blaziken can't hold a candle to Primal Groudon... literally nothing can. So why is it up here in the Supreme Mega Evolution counters list? Because it's the best Fighting Type Mega Evolution in the game, meaning it provides a an extremely valuable boost to all of the best Fighting Types. This alone puts it just over the edge and makes it one of the two Mega Evolutions that are on the forefront of this raid. 

Good Mega Evolution Counters

Mega Garchomp Mega Garchomp
Fast MoveCharge MoveRating

Mega Garchomp actually had higher average performance than Mega Blaziken, especially thanks to its triple-resistance to Thunder. However, it really doesn't appreciate facing down Dragon Type moves, and in practice it's basically a worse Primal Groudon.

Mega Lopunny Mega Lopunny
Fast MoveCharge MoveRating

While definitely below the competition as a Fighting Type, Mega Lopunny is still a decent backup Mega that can make Fighting Type teammates all the more useful in the absence of Mega Blaziken.

Mega Swampert Mega Swampert
Fast MoveCharge MoveRating

A good filler for a Ground Type team, Mega Swampert can help boost Ground Types in the absence of the all-important Primal Groudon.

Supreme Counters

shadow_excadrill Shadow Excadrill
Fast MoveCharge MoveRating

Shadow Excadrill hits like a truck, and has its middling bulk patched up by the fact that it resists everything that Dialga can throw at it, even double-resisting Thunder. Add to this the fact that it can be passively boosted by just having Primal Groudon on the team, not even active, and it should be pretty obvious why Shadow Excadrill is the top non-Mega/Primal counter for this raid.

Terrakion Terrakion
Fast MoveCharge MoveRating

The top Fighter... has some issues here. It works extremely well in general, but its weakness to Dialga's Steel Type moveset makes it pretty easily picked off without some good dodge-timing. That's not to say it's bad by any means, but it's also not quite perfect.

Shadow Garchomp Shadow Garchomp
Fast MoveCharge MoveRating

Shadow Garchomp, much like its Mega forme, doesn't like Dragon Type moves. However, it's still a strong performer that can throw out extremely strong attacks while triple-resisting Thunder.

Shadow Machamp Shadow Machamp
Fast MoveCharge MoveRating

The one true vanilla Fighting Type, Shadow Machamp works well and has no major issues here.

Shadow Hariyama Shadow Hariyama
Fast MoveCharge MoveRating

While a bit worse than Shadow Machamp, it's still great.

ShadowSwine Shadow Mamoswine
Fast MoveCharge MoveRating

While fairly high on the DPS chart, Shadow Mamoswine doesn't like facing down Dialga's Steel Type moves.

Fast MoveCharge MoveRating

Baby Keldeo doesn't care for Thunder, but at least it resists Steel Type moves.

Good Counters

Lucario has a great set of resistances for this raid, resisting everything that Dialga can throw its way save Thunder.
