I might go into details now...
Strategies: Send out Fire pokemon against Grass pokemon, duh. And I also teach a wide variety of moves to my pokemon (especially with my Sceptile) so that it has more effect on different types.
Jobs: No jobs really, I only use my Dragonite for Fly and my Swampert for Surf.
EV Training: Still not entirely sure about what Ev's even are, unless you mean the pokemons stats? (I know, weird huh?)
