Aggron mega: Unranked -> c
Excellent typing in mono steel with 230 defense makes Aggron a worthy alternative to Registeel and Steelix-mega. It has higher attack than either of them allowing it to hit stuff hard with a stab move such as Anchor or Sunsteel (I suggest Anchor to trap Imposter). Sunsteel does a huge amount to Tyranitar-mega though, almost an OHKO after stealth rock, and hits Shedinja. It also can KO Normgar with Steelium-Z but it has only 8 pp which means you'll probably run out quicker than you'd like. Overall it's a niche pick that's especially good for improofing or stallbreaking better than Registeel due to its stronger offenses.
Sets:
Other sets to consider include Mold Breaker and Simple Smash, which are kind of inconsistent but can really screw up your opponent's game if the matchup is good and you play them right. Definitely worth a spot on the VR though.

Sets:
BabyBabyBabyO (Aggron-Mega) @ Steelium Z / Leftovers
Ability: Soundproof
EVs: 252 HP / 252 Atk / 252 Def / 252 SpD
Sassy Nature
IVs: 0 Spe
- Anchor Shot
- Shore Up
- Poison Fang
- Rapid Spin / Parting Shot
A worthy check to many Mega Diancie sets that run Boomburst + Ground or fire coverage. Can also trap Imposter, and it can usually force a spin against all but Poison Heal or Comatose Giratina with Poison Fang. Steelium-Z boosted Anchor Shot deals about 80% to Normalize Mega Gengar,, which isn't enough to kill, but leaves it in easy range of chip from even Mega Diancie's Pixie Plate Extreme Speed. You can also run Parting Shot with Darkinium-Z.

HeavyMetalMan (Aggron-Mega) @ Assault Vest
Ability: Regenerator

Sassy Nature
IVs: 0 Spe
- Sunsteel Strike
- U-Turn
- Nuzzle / Spectral Thief
- Core Enforcer / Rapid Spin / Knock Off
Regenvest is a nice sturdy check to stuff like Mega Diancie, Kyurem-W and Kyurem-B, all of who are punished severely for trying to push the issue with Sunsteel, far more than Registeel would anyway. Greater physical bulk lets it comfortably live boomburst into v-create from Mega Diancie as well as Boomburst into v-create from Kyurem-B. It can also handle things like Specs MMY's Adaptability Psycho Boost or Psystrike very well (tinted Lens is still a 2hKO). Unfortunately, it still loses to Normalize Gengar.
