252 ATK 128 SP DEF 128 DEF
________<--idk donphan's ability
Offensive spinner, one more move..
252 SP ATK 128 DEF 128 SP DEF

I like Milotic as a solid water/ice, but I need 1 more attack. I'm sure I had one but I forgot...
The rest of the spots are open, but looking at this I want an entry hazard Pokemon with Toxic Spikes and Stealth Rock, and a good solid Waller staller/tank. Also, I'm not really looking at tiers right now.
