Dusknoir: i am great at predicting. Sometimes i take out focus punch for sub, and i use sub. They switch, and i use pain split or will-o-wisp (because they expect FP)
For swamp: sometimes i use my other swamp, and he has Ice beam instead. Or i use my Curse avalanche swampert. Thing is, i have many diffrent versions of these lol.
And thanks, these are my gimmicks that work awesomly.
I Baton pass usually to either breloom, or dusknoir
(i have a punch set)
