Mega Aggron Sandstorm

Synergy

Mega Aggron is the creative centerpiece, using Iron Defense + Body Press to snowball off its enormous Defense stat (nearly 300 without full investment). Filter reduces super-effective damage, making it extremely hard to remove. Sinistcha's Hospitality heals Aggron on switch-in, and Rage Powder redirects moves to protect it while it sets up. The team can also function under Trick Room.

Win Conditions

Set up Iron Defense with Mega Aggron to reach monstrous Defense and deal huge Body Press damage. Use Sinistcha's Hospitality and Rage Powder to keep Aggron healthy and protected. Garchomp and Tyranitar provide offensive pressure to prevent the opponent from stalling.

Lead Options

Aggron-Mega + Sinistcha, Aggron-Mega + Incineroar, Tyranitar + Garchomp

Threats

Special attackers that bypass Filter, Fighting-type spread moves, fire types that threaten the steel core.
