Team 2 has covered team 1 pretty well now.So it's time to add something that puts extra offensive pressure.Thus I nominate Terrakion.I was initially thinking of SubSD set but decided to post CBTerrakion for it's ability to hurt Landorus-I and Rotom-W hard right away.

Terrakion @ Choice Band
Trait: Justified
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Close Combat
- Stone Edge
- X-Scissor
- Quick Attack
Standard CB terrakion.Rock+Fighting provides nearly universal coverage and with Terrakion's 129 attack stat and STAB on both them as well as 120 and 100 base power of Close Combat and Stone Edge makes Terrakion nearly impossible to switch into.X-Scissor and Quick attack are fillers.X-Scissor hits physically defensive Celebi and Slowbro harder while quick attack picks of weakend threats.Terrakion puts immense offensive pressure on Team 1 and is impossible to hard counter.
Heatran and Keldeo checks Scizor nicely,one of Terrakion's main revenge killer,while Celebi takes care of potential Breloom.Terrakion busts open lots of pokemon assisting Team 1 greatly.It's powerful physical presence also comes in handy as Team 2's all 3 picks are special attackers.
