Aggron is legal in Regulation M-B and did not appear often enough on the ladder to produce usage statistics. It is legal and simply out of favour, which makes it unmeasured rather than unusable.
Aggron is number 306 in the National Dex, a Hoenn Pokémon, Steel and Rock with a base stat total of 530 — 49th of the 234 Pokémon legal in this regulation. Its best stat is Defense at 180, 4th in the format; its weakest is Speed at 50, 196th. It can have Sturdy, Rock Head and Heavy Metal. The Champions module tiers it UU.
It sits in a 3-stage line: Aron → Lairon → Aggron. Not all of that line is legal in this regulation — Aron and Lairon are not.
As Steel and Rock, 3 of the eighteen attacking types do extra damage to it, and Fighting and Ground land for quadruple. It resists 8 and is immune to 1. The board above has all of it. One other legal Pokémon shares the same typing and the same board: Bastiodon.
Smogon publishes no head-to-head checks-and-counters data for doubles formats, so this list is computed, not measured: the most-played Regulation M-B Pokémon carrying a damaging move of a type Aggron takes extra damage from.
At level 50 with a boosting nature and full investment, Aggron reaches 112 Speed; left uninvested with a neutral nature it sits at 70. Invested, it outruns 0 of the 20 most-used Pokémon in the regulation when they are invested too — which is the comparison that decides who moves first.
It weighs 360 kg, so Grass Knot and Low Kick hit it for 120 base power. That is a real consideration in a format where both are common.
Aggron learns 124 moves in the Champions data. 81 of them do damage, across 15 of the eighteen types, and 16 share a type with it and so get the same-type bonus. Its hardest-hitting same-type move is Head Smash at 150 base power. It has no priority move, so it moves in Speed order every turn.
That pool is what the team builder reads from when you seat it, and the damage calculator will take it as the attacker with the form already chosen.
