Overview

Requests to split into small groups for Mewtwo are inevitably met with heavy resistance. With such a powerful, exclusive species, this is understandable. However, Mewtwo is among the easier tier 5 bosses. Odds are that if you regularly read GamePress, you have the resources to be part of a Mewtwo trio.

Tyranitar and your own Mewtwo are often going to be the best choices, but over 20 unique Pokemon are capable of beating the clock without weather boost in a Mewtwo trio. Optimal parties can heavily depend on the moves that Mewtwo has. After the egg pops, have one brave soul enter the raid to determine what moveset you are up against.

Etiquette

While some communities are lucky, not everyone has an easy time getting an EX Raid Pass. Please don’t exclude anyone because you desire the glory of a trio. Try to make sure that everyone can complete the raid. Don’t be an asshole.

Approach

Team composition

  • Tyranitar and Mewtwo are safe bets, effective against 3/4 Mewtwo sets

  • Vs. Focus Blast, Tyranitar is glassy, while Gengar and Dragons do well

  • Lesser counters are only viable vs. certain charge moves - check first!

Dodging strategy

  • Re-entry may be necessary depending on set, especially vs. Confusion

  • Dodging is usually not necessary, though it can help to prevent re-entry

  • Do not dodge Focus Blast with Tyranitar, Shadow Ball with Gengar, etc.

Note: "Good" movesets are not necessarily viable at the level indicated.

Matchups

Countering Mewtwo can be tricky because different Pokemon are good against different movesets. Here's a quick overview of what you should bring depending on Mewtwo's charge move.
