Remember how in Bonds Beyond Time, Malefic Paradox Dragon revived Stardust Dragon even though it was improperly Summoned? Now you can pull that off legally!
Sin Paradigm Dragon / Malefic Paradigm Dragon
DARK Dragon / Special Summon / Effect
Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand) by banishing 1 “Malefic” monster from your Extra Deck while “Malefic Paradigm Dragon” is not on the field.
(1) If “Malefic World” is not on the field, destroy this card.
(2) Once per turn: You can send 1 “Malefic” card from your Deck to the GY; you cannot attack for the rest of this turn, except with “Malefic” monsters, also return 1 of your banished Level 8 Synchro Monsters to the Extra Deck, then you can Special Summon that monster from the Extra Deck.
