How to unlock Mewtwo
Use the Kanto banner for its 5-star pool. Its legendary flag also makes it eligible for a legendary rift encounter. Pool rolls select uniformly inside a rarity; pity and ten-pull guarantees can change the rarity chance. This is an unlock route, not a guaranteed targeted pull.
Starting attack and first evolution
Max Confusion at level 5, take the Reflexes run card, then choose Psyshock on the gold card.
Build from its legal move pool
Its psychic typing lets it learn Normal moves plus moves matching either type. Compare the complete pool below before selecting four slots. Base HP, movement speed and damage multiplier are game-specific; permanent upgrades and run cards modify them. Only the active unbonded slot attacks.
