>>19902825Fire Fang is weaker, but definitely gives it coverage on steel types that may give it trouble otherwise. Things like infuriating Klefki can be dealt with if you have it. It also works against Aegislash; Sucker Punch is awesome because it won't activate King's Shield, but this is usually anticipated, so generally, Aegislash players will try to use priority on Mawile to avoid a Sucker Punch. But if they EVER use King's Shield, Fire Fang is your safest bet because they will likely attempt priority, and even if they don't, you still have some crazy-super attack ontop of a supereffective move.
My suggested set is Fire Fang, Play Rough, Swords Dance, and Sucker Punch... I recommend setting up a barrier for the type of attackers you will be facing first though. Either Light Screen or Reflect. Brick Break won't really hurt it.
