PSA: Armarouge is an extremely good support mon for the Cinderace raid

I've been having great success with Armarouge for the Cinderace event. Here are a couple of reasons why:

Flash fire and psychic typing to resist both Pyro ball and High Jump Kick. I've done this raid many times, and so far the ONLY attack it has used against my Armarouge has been Acrobatics, which doesn't do much damage against its good physical defense.

This biggest initial threat is Bulk Up, as once it uses it enough times, the fight will quickly snowball against you. This is where Armarouge's great support moves come in. This mon has Reflect, Taunt, and Clear Smog. Reflect is essential for survivability, so I also use the item Light Clay to extend its duration to 8 turns.

Taunt is used to prevent it from using Bulk Up. Clear Smog is for removing its stat changes at the start of the fight, as well as when its barrier is up as taunt no longer works then.

I'm running the above three moves along with Lava Plume, which I use when Cinderace's barrier is up and I don't have anything else to do. Lava Plume has a 30% burn chance (which halves its physical attack) and unlike Will-O-Wisp, will apply burn through its barrier.

I usually open the raid with Reflect --> Clear Smog --> Taunt --> Cheer Defense. This will nullify the Bulk Up it uses at the start and set your team up with good defenses. This will help enable your attackers to do their job much better (Cheer defense is extremely good, and not enough people use this! In my opinion, survivability is vastly more important than quick damage in difficult raids).

Side note, Ceruledge is also good for this raid, as it also comes with reflect, taunt, clear smog, and lava plume. Though, personally I find Armarouge's higher physical defense to be more valuable. Ceruledge's ghost type isn't really better than Arma's psychic type in this case, as Cinderace won't use its High Jump Kick against either of them.

This is by no means an authoritative guide, and no doubt there will be better strategies found. However, if you're stumped on running a mon for this event, I highly recommend Armarouge for the reasons above. Good luck and have fun!
