Magikey Battle (BODE-EN062) - Burst of Destiny 1st Edition

Target 1 Normal Monster, 1 "Magikey" monster, or 1 "Magikey Maftea" in your GY; shuffle it into the Deck, then if you activated this card in response to your opponent's card or effect activation, Normal Monsters and "Magikey" monsters you control (except Tokens) are unaffected by that opponent's card effect.
