OnceDone, please ignore his advice, as he still has quite a bit to learn about Pokemon.
@Jaws That Gardevoir sucks, and by that I mean sucks hard. Use Calm Mind l Psychic l Focus Blast l Shadow Ball instead, it's much better for ingame, since Fire Punch is Physical.
That Weavile needs Night Slash instead of Pursuit, otherwise Jaws' set is decent.
Keep Froslass to help with your Fighting weakness, as it's part Ghost.
Magmortar is better than Magmar by far, so use that instead.
Turn the radio up, and we can have a good time
