Am I the only one who thinks that this thing is actually gonna be a really decent stallbreaker thanks to the unprecedented ability to Toxic almost anything in the game? Plus it has high Speed and access to Taunt.

Toxic + Taunt will let you singlehandedly break down passive stall teams and seriously annoy fatmons in general. Fire Blast + Sludge Bomb offer STABs, cause his movepool isn't exactly amazing and there isn't a whole hell of a lot else to put there. Substitute can be used to further aid in stallbreaking I suppose. While it's kind of a strange set, it's also really simple. Toxic things, Taunt defensive Pokemon, Heal Bell users, etc. That's basically it.
Obviously needs some serious team support, being as it has perhaps the worst possible defensive typing in the game (other than, like, Ice/Fire...), but on teams that really need a reliable stallbreaker, Salazzle might be worth consideration.
