hey, I'm agree with all Neliel already said. I'd only add you should use Tyranitar with 100 Evs on Speed, to outspeed some fast version of Jellicent and to smash them before they Will-O-Wisp you and as well to outspeed Skarmory and 2HKO it with Stone Edge (use it with 252 EVs in Atk, it's just better imo on CB TTar as yours...), that's all i guess, gl
