adanment
____________
wood hamer
stone edge
rest (w chesto berry)/???

Not only does torterra have defense and offense AND a good typing but the element of surprise. who expects a torterra in the OU? NOBODY!!!!!
that is his key advantages

@ leftovers
252 hp/ 252 atk
adanment
_________
No Guard
Dynamic Punch
Stone edge
rest
sleep talk

he is like torterra without the overly awsome typing and awsome looks high stats but low surprise

Thanks for your help as this is the last problem in my party

Uhhhh.... Torterra has quite bad typing, it's 4x weak to ice which is a common move in OU for dragons and also weak to fire, flying and bug. Fire is somewhat common as well. and it's 2 resistances is a bit limited but ground/rock are both common types so it can have some use.

With torterra I'd go with either swords dance and EQ over rest or if defense is more so needed make an Impish one and add sleep talk.

Machamp is Machamp, for choosing I'd go with whichever can switch in better with your teammates.


and it's spelled adamant.
