>>30501585Neither, the right answer is Roxie.
-"Fight with this Pokémon that way... Use this item that way... Are you letting others decide that for you? Well, whatever, but what's important is figuring out what you want to do!"
Giving your team what you feel it needs is important, and honestly Roxie is the only one that touches that subject, she is smogon as fuck in that regard optimizing your team according to what you want to do is pretty much the very foundation of the smogon format.
Karen is shrouded in faggotory, since strong and weak Pokémon doesn't matter I should just use my favorite, well prepare your anus for some mega fug because it's very hard for me to dislike Choo choo Shenlong. I'm not using him because it is strong, I'm using him because the design appeals to me! Funny enough Smogon usage tiering kinda allows even shitmons to shine in their context.
ORAS gentleman is absolutely right about VGC and to some extent about patching holes in singles team building. Centralization is real, and to be competitive you gotta play its game, both with it and also in the anti meta sense.
But seriously Roxie gives a damn good piece of advice.
