I feel like he could be 5 ft tall and 150 pounds (or does pokemon use metric?) Anyway, someone mentioned fair fight as a name for the ability. As a pirate, the ability name should be something exactly opposite of that...he's a pirate after all!
Orlando Bloom: I would have beaten you in a fair fight!
Jonny Dep: Not much incentive to fight fairly, is it mate?
So maybe a name like "Sneaky Tactics" would better suit him.
