Return by Death (RZ/S46-E094 U) [Re:ZERO]

Brainstorm Flip over three cards from the top of your deck, and put them into your waiting room. Choose a level X or lower "Magic" or "Weapon" character in your waiting room, and return it to your hand. X is equal to the number of "Magic" or "Weapon" characters revealed among those cards. Choose one of your characters, and that character gets +2000 power until end of turn. Put this card into your memory. (Red text indicates official errata.)
