I don't think a special attacking M. Beedrill could work.
But I guess if you're insane enough to try:
252 Sp. Attack, 252 Speed, 4 Def
Sludge Bomb (Strongest stab special move it gets)
Hidden Power Water/Ice/ground (Cover weaknesses, you're fast so you might pull it off)
Double Team (You're going to need more than one turn)
Toxic (You're not doing much damage, so use this to help)
