I REALLY hate to fight against and play as stall, so i made a hyper offense team so i can get past stall without forfeiting the quickest way possible. The thing is: This team sucks. I'm trying to use fast, hard hitting, and Smogon-approved Pokémon, but i'm not winning many battles at all. I won't be removing Staraptor, so don't tell me to get rid of it (in fact, Staraptor is actually the most effective mon here). Is there anything i can do? Here's the team:
