Alright, so my nomination...
Garbodor @black sludge
Trait: Stench
Evs: 252 Hp, 160 Def, 58 spe, 40 Atk
Nature: Impish (+ Def - spA)
-Spikes
-Toxic Spikes
-Rock Blast / Gunk Shot
-Clear Smog
All in all, garbodor serves as a safe switch into sawk thanks to good defence and poison typing. This also lets him absorb toxic spikes and lay them down as well. Clear smog makes him not set-up fodder, meaning he can take on some set-up sweepers as well.
