Ability: No Guard
Dynamic Punch. (Deals a lot of damage, and when it hits, it will confuse target) <-- A must have
Cross Chop. (A good finishing move, just like Dynamic Punch without confusion and a little more accuracy)
Stone Edge. (Deals with Flying Types, does a lot of damage. Nuff said)
Payback. (Also A must have, deals with Psychic types, if used after opponent, deals double damage)
Three of these moves deal 100 Base Damage, with one that has 100% Confusion on the opponent if it hits. And the last one will also deal over a 100 damage if it goes after the opponent.
These are all the moves that my No Guard Machamp has and they work extremely well.
Hope I helped :P
