I know Salazzle is good, but i think he could have instead of fire bolt or fire pledge flamethrower like salandit has, and/or toxication to make him bit more last longer, maybe too much but think about it
I would like to suggest change instead of adding toxication as Salazzle have one stunning move.
Poison gas which is aoe stun, but blocks only some enemy's moves for toxication which have pretty nice dmg and is also aoe stun.
poison gas is op skill but, i have one problem with it, when wild poke is using it , i cannot use any move,if im using poison gas wild pokes sometimes goes through this "stun", it shouldnt happen in my opinion
