Thought I'd share this new set I've been testing out.
Drifblim @ Flame Orb
Ability: Flare Boost
4 HP/252 SpA/252 Spe
While everyone runs around with Unburden Drifblim, its dream world ability is laid to waste. This ability gives Blim a Special Attack boost when it is burned, similar to Zangoose's Toxic Boost (with the attack stat). The idea is simple, set up a protect to activate the orb and then you can attempt to clean up. The last moveslot is gimmicky, seeing as Drifblim doesn't have amazing coverage. Rest is what I use, even though it removes the flame orb, when you wake up it will activate again. Will-o-wisp is also good for crippling opponents and T-wave is important if you predict a switch. Psychic is another coverage option, but chances are that no one will be switching in a fighting type. Sleep talk doesn't work well with this set, but if you really wanted to, it could be used over protect. All in all, this set is surprising to many users and it can work well with the right support.
