It is legit if it is from the bonus disc I think (although I think it won't say from Hoenn..) Celebi is the only Pokemon I don't have. Moveset:
Recover: Heals Celebi.
Calm Mind: Increases special stats.
Energy Ball: Good power, STAB, chance to lower Sp. Def, high accuracy, deals with Rock, Ground, and Water types.
Psychic: Good power, high accuracy, STAB, chance to lower Sp. Def, deals with Poison and Fighting types.
