I know about STAB moves, and as you see, ALL of my Pokemon use both of their stab moves. As for Acrobatics, I'M PLAYING DIAMOND!!! There's no Acrobatic there. And getting rid of Steel Wing? I use Steel Wing to beat Rocks. Giga Drain on Tenta is for coverage, as I already have a Poison move. Poison Jab would be an option over Sludge Bomb. Drapion has very high defense, and not only high attack, so I wouldn't see why it can't spike. I would like to see a better option though. And I will run Either Brick Break or Focus Punch with Substitute. Also, Focus punch is one turn, just has an OTHER side effect.
