1.) Save Stall!
2.) Weather Slayer
3.) Momentum
Love all of these ideas, but the stall idea seems the best. Stall faces so many problems that even the best stall teams have gaping holes. Pokémon like Burunkeru help and hurt you at the same time (good spin blocker and special rain check, but it's defenses seem like they should be switched for it to perform much better) , and I would love to see stall still be able to work.
