For jax, hes my main, so i suit him like hybrid early, but then take some AD

Teemo, hes much more better like a carry, since he has high attack speed, i use on-hit effects

Twitch, a bit like teemo but has no mush and a bigger range, really usefull!!

Kassadin key is to stack damage on riftwalk by teleport often, it cost a lot of mana. since he is squich he need a lot of AP to destroy ennemies fast and spell vamp at the end.

renekton, I like him to hit really hard even if he is squich like that, you can normally easyli 2v1 even with that he is too OP
