Actually, this has gotten me to think of a weird Dugtrio set that could trap and kill Wobba. How ironic
Dugtrio @ Life orb
EV's:252 Atk/252 Speed
Ability:Arena Trap
Nature:Adamant
-Toxic
-Substitute
-Earthquake
-Sucker Punch/Stone Edge
No matter what Wobbaffet does, it's trapped and going to die. You also end up with a sub :]
Dugtrio really doesn't need a sub.. I'd much rather have him able to revenge kill Hera / Breloom with Aerial Ace. Life Orb is also for personal preference [Choice Band can still be used here], since you'll be forced to use Toxic anyway if you don't wanna get 1HKO'd by Counter.
