It should also be noted that, depending on your team, some EVs can be shifted from Special Attack to Attack to obtain the OHKO on certain threats with U-turn: 68 EVs (with an Attack boost) for Serperior, 104 EVs for Deoxys-S, and 112 EVs (with an Attack boost) for Latios.
oh yes! 21 HP IVs gives it 201 HP which means it can take 2 Chansey's Stosses (and take 1 Stoss after 2 Subs), you can run a little hp to make it so that you can live rocks + 2 stoss but i dont run that xD.
Amoonguss i just wanted to be more of a mixed wall, those EVs arent too great though looking back. Run 28 Special Attack EVs and 12 Speed EVs. 28 Sp.A breaks +1 Keldeo's Sub with Giga Drain 100% of the time, 12 speed outspeeds most other Shrooms and Reuniclus...you can play with the defensive EVs as you wish, pump a lot of HP always tho.
152 Speed on Gene outspeeds Scarf Rotom W and I always LOVE strong U-turns so I pumped that a lot, you can also play with Gene's EVs (most people like max Sp.A)
idk! the rules aren't out yet, but i'm hoping they'll be the same, just with bw2 tutor moves available. i wouldn't mind another year where they allow ubers, but i think trick room will be as strong as ever in whatever format they choose (as long as it's not something besides doubles)
