When this card is Normal Summoned: You can add 1 Spellcaster-Type monster with 1850 ATK from your Deck to your hand. Once per turn, during either player's turn: You can target 1 face-up monster your opponent controls; your opponent can send 1 monster with the same name as that monster from their Main Deck or Extra Deck to the Graveyard to negate this effect, otherwise return both this card and the targeted monster to the hand.
