How to unlock Arceus
Use the Sinnoh 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 Tackle at level 5, take the Vigor run card, then choose Take Down on the gold card.
Build from its legal move pool
Its normal 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. Judgment Arceus is a separate invincible endgame encounter; these partner stats do not make that boss killable.
