So Mawile has always been a pretty under appreciated pokemon as far as i know and late in the hayday of Heart Gold and Soul Silver, i realized what a incredible physical wall it can be in the low tiers and it's many crippling abilities. With the addition of black and white coming out, he got a really useful ability and access to use Metal Burst which can give it some really good attacking options. Here are just some things that I brainstormed.
Pure Attacker:
Mawile @ Life Orb/Choice Band
Ability: Encouragement
EVs: 128 HP/252 Atk/128 Def
Nature: Adamant
~ Iron Head
~ Crunch
~ Fire Fang
~ Rock Slide
Basically, the idea behind this set is to abuse the encourage ability as much as possible. Since all four of the moves have an additional secondary effect, their power will be boosted by Encourage, but their secondary effect will be removed. Mawile has a ridiculously move pool to utilize this ability and the four attacks above can pretty much hit about anything. Also, your speed is garbage so you wouldn't be able to flinch anything anyways and the chance of a drop from crunch or a burn from fire fang hardly ever happen anyways. According to the research thread, dreamworld abilities are breedable and since smeargle is in your egg group, you have nothing to worry about.
Pure Defense:
Mawile @ Leftovers
Ability: Intimidate
EVs: 252 HP/6 Atk/252 SpD
Nature: Careful
~ Stockpile/Iron Defense
~ Baton Pass
~ Payback
~ Stone Edge
This set is there to utilize the resistances that come with his pure steel typing and his ability to baton pass if necessary. Since Mawile's physical defense is pretty good, this set focuses on getting his special defense up to a useable level. You have your choice of stockpile to raise both defenses and iron defense to double your defense. Both of these boosts can be baton passed and whatever receives them will generally benefit greatly. As for moves, payback is your best option because you are really slow so it will almost always have 100 power and with increased defenses, you have the potential to do more damage to your opponent than you receive. Stone edge is there just to show off that Mawile can now learn it and because an increased chance of a crit is always welcome.
Pure Sabatoge:
Mawile @ Leftovers
Ability: Intimidate
EVs: 252 HP/6 Atk/252 Def
Nature: Adamant
~ Toxic
~ Sucker Punch
~ Super Fang
~ Metal Burst
This set is my favorite Mawile set and one that i used on Shoddy a lot, except for Swagger being where Metal Burst is. Basically, this set gives Mawile the potential to do a ton of different things to your opponents. You can inflict toxic poison, revenge kill with sucker punch, halve their HP, and KO them with a well timed metal burst. The EV spread also allows you to take physical hits really well and with metal burst as a option now, you can send that damage right back at them and sucker punch for the kill if metal burst fails to KO. You essentially can't go down without doing something to hurt your opponent and this is what gives Mawile extreme versatility.
