Right.. let me make the first argument for pete then. He's as skilled with his hot knives as Gambler is with his cards. He managed to hit three shurikens at the same time heading for him. So he should be able to manage against Gambits cards. He's a highly skilled fighter. He can makes his knives hotter then the surface of the sun and uses theses as claws coming from his fingers.
I think he should be able to hang with Gambit.
I do hate Pete Wisdom, make no mistake about that. Guy's a pedo. Literally.
That doesn't change the fact that Gambit is faster, more accurate, has better firepower and better hand to hand skills. Across the board, Gambit wins in every way.
