Overview

Originally Aggron was one of the toughest duos in the game, with only a handful of trainers on the planet completing it. The raid required weather boost, maxed champs, and great RNG. With the introduction of Friendship & the CP rebalance, Aggron got significantly easier and became beatable without
boost. Now with the type effectiveness change, this duo offers little to now challenge, even if trainers try to win with 12 unique Pokemon.

Approach

Team composition

  • Machamp & Breloom are best

  • Many other Pokemon with fighting moves are viable

  • Groudon becomes the best counter in Clear weather

  • Occasionally you may need to re-enter. Make sure that at least one trainer is battling Aggron at all times so it does not regenerate health

  • A second team is recommended as max reviving is too slow

Dodging strategy

  • Dodging is no longer needed

  • Be aware of the dodge glitch death loop when dodging

  • While fast enough, Primeape is very fragile. Two teams of 6 would need to re-enter

  • It can still be solid filler
