Best attackers by type

Editor's verdict

The best Psychic attacker in the game and a versatile generalist. Two Mewtwo with Confusion and Psystrike (Elite TM the move if you can) cover Psychic raids and flex into Master League. A near-mandatory build.

Catch CP after the raid

The CP you will see on the encounter screen.

IVs	Lv 20 CP	Lv 25 CP (weather)
10 / 10 / 10 floor	3,643	4,532
15 / 15 / 15 100%	3,765	4,683

Raid catches have an IV floor of 10/10/10, so the two rows are the real minimum and maximum. If you see 3,765 CP it is a perfect Mega Mewtwo Y — throw a Golden Razz Berry.

Raid guide

How the fight goes and what to bring.

Mewtwo is pure Psychic, weak to Bug, Ghost, and Dark. Counter it with Ghosts (Gengar, Giratina), Dark-types (Tyranitar, Hydreigon), and Bug attackers. Beware: Mewtwo sometimes carries coverage moves like Focus Blast or Shadow Ball that punish specific counters, so check its moveset before committing a team. It's a hard duo and best with 3+ trainers. Psystrike Mewtwo is elite for both raids and Master League, making it one of the most valuable legendaries you can invest in. Shadow Mewtwo, when available, is the raw-DPS ceiling.

Mega Mewtwo Y resists Fighting, Psychic — leave those attackers out even if they are your highest CP.
