I'm a big fan of Autotomize/Earthquake/Heavy Slam/Fire Blast after giving it a try. It's tailor-made for cleaning up games and I've been so surprised.
Celesteela @ Leftovers
Ability: Beast Boost
EVs: 252 Atk / 4 SpA / 252 Spe
Naughty Nature
- Earthquake
- Heavy Slam
- Fire Blast
- Autotomize
With max speed and a neutral nature you outspeed Pheromosa by one point after an Autotomize. The best part about this set is that it can seal games if the opponent is expecting the standard defensive Celesteela, which often doesn't carry Earthquake. If you Autotomize on a switch to Koko/Magnezone/Heatran/anything frail enough, you can kill them off the next turn and rampage through the opponent's team thanks to Beast Boost. By way of its bulk and typing it can set up extremely easily and hurt offensive teams.
As the metagame develops people might start running HP Ice paired up with Magnezone so that they can break through Lando-T, Gliscor, and Garchomp, all of which make sweeping hard. Giga Drain too could see use although it doesn't do a whole lot to Slowbro without investment. Celesteela's ability to pick its checks is pretty great and will make this thing more threatening once people diversify from Leech Seed a bit.
