How's this sound?
Binding band and whatever EVs/ability you like
Wrap/sand tomb
Toxic
Protect
Rest
Toxic first, then wrap, protect, rest = 4 turn KO
toxic spikes would help a ton but toxic deals 10/16 HP in 4 turns and the other 6/16 is from wrap
I also have a friend who uses acupressure, rest, EQ and stone edge, only 4th gen but he claims it works well
I wanna try pull off a power trick/trick room sweep in a double battle though :D
