Territory of Malice
Return 1 "Malefic" card from your hand to the Deck, and add 1 "Malefic Territory" to your hand from outside of your Deck. Then, you can add 1 "Malefic World" to the bottom of your Deck from outside of your Deck. This Skill can only be used if you begin the Duel with a Deck (excluding Extra Deck) that contains no monsters other than "Malefic" monsters and Dragon-Type monsters. This skill can only be used once per Duel.
