I've got a kinda... strange idea. HAIL TEAM!
EV's: 252 HP, 252 Def OR 252 Sp Def, 4 Atk
Ice+ground combo, Blizzard has great power and 100 accuracy in hail, and earthquake is all around amazing. The nature is all up to what your team needs, whether it be a special or physical wall. Anyway, Give the foe a status condition, and protect, attack, repeat. Scald is only 20%, so it's kinda, ehh... but it might work.
Now for one more... Dragon Dance. I have a somewhat interesting idea for this one...
item: life orb
252 speed 252 attack 4 hp
Yes, spark. Low base power, but it has a good chance of paralysis. With paralysis, you don't even need the speed from Dragon Dance. Then the other moves for stab.
All right, that's about it for my strange ideas. It's time for me to go to bed, I'm tired.
