Source of The Curse (RZ/S55-E050 U) [Re:ZERO Vol.2]

If you have 2 or less "Magic" or "Weapon" characters, this card cannot be played from your hand. Draw up to 2 cards, choose 2 cards in your hand, put them into your waiting room, choose 1 of your opponent's characters, that character gets -1000 power until end of turn, choose 1 of your characters, and that character gets +1000 power until end of turn.
