EVs would also be great here.
Shell Smash > Dragon Dance on Smeargle. Spore should be enough to not let the defensive drops be a concern. Something to make the BP easier, like Magic Coat or Taunt, is also preferred in the last slot. Either find someone else to set up SR or just make do with Roserade (because it already can set up Spikes).
Definitely use Fire Punch on Flygon; since Flygon is fast, Dragon Tail's negative priority is a detriment here; IMO, it's better off on support sets.
Blastoise can be your Rapid Spinner for the team because Darmanitan is weak to Stealth Rock and Smeargle hates having its Focus Sash broken:
-Scald
-Rapid Spin
-Toxic/Foresight
-Roar/Dragon Tail
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Torrent
You could disguise Zoroark as Roserade because Roserade discourages the opponent from using the Fighting moves that Zoroark is weak to (since Roserade resists Fighting).
Thank you for the advice! I didn't notice when I was looking at the Serebii move list however that flygon only learns Fire Punch in B/W2 which is not out yet. The small tournament I am bringing this team to, will be taking place a good while after B/W2 come out, but it will still be on the first game. Would you consider it cheating if I where to port a Fire punch knowing Flygon from White 2 to my White game?
Would Dragon Claw be a good stand in for Fire Punch?
I didn't think to have Zoroark disguised as Roserade, so thank you for that.
I switched around Smeargles move list, taking Shell Smash like you suggested and grabbed Magic Coat instead of SR. I chose to go with Toxic and Roar on Blastoise to keep the accuracy. (I'm not seeing anything with Soundproof or Suction cups..., or is the 90% accuracy the better choice because of the slight damage it deals...?)
