Haha, yeah lol. Breloom and Machamp are annoying. Breloom is really a pain since it can set up on so many different things, and Machamp is annoying because there is like nothing that can KO it hold a boosted move/using Psychic which is a poor attacking type.
So basically Machamp will live anything/force a switch, and confuse something with Dynamic Punch, unless they switch into a Ghost which would get killed next turn. Machamp just doesn't have many safe switchins and it hits really hard.
