I used to always run this back in gen 4. Too much priority to really make the most of it though.
UtilityScarfSmeargle Jolly / 252 Spe 252 atk or hp / Choice Scarf - Spore - Trick - Lunar Dance - Explosion / Momento
Spore the lead and come back to cripple something with trick or revive my own sweeper when it has been crippled. Explosion or Momento to help you set up for the next pkmn. It had some other move but cannot think of what it was. Stab Explosion bloody hurt too before the nerf
