Malefic Territory

Effect

When this card is activated: You can activate 1 "Malefic World" from your Deck. While that card is in the Field Zone, neither player can target a card(s) in the Field Zone with card effects. The "Malefic" monster effect, "There can only be 1 face-up "Malefic" monster on the field" becomes "There can only be 1 face-up "Malefic" monster on the field with the same name". During the Battle Phase, negate the effects of face-up "Malefic" monsters on the field.
