Nightmare Throne

When this card resolves, you can take 1 Fiend monster with 0 ATK/DEF from your Deck, and either add it to your hand or destroy it. Once per turn, if a face-up "Yubel" monster(s) you control leaves the field by card effect: You can add 1 of your "Yubel" monsters that is 1 original Level higher or lower than 1 of those destroyed monsters and is banished or in your Deck or GY to your hand, then you can Special Summon it, ignoring its Summoning conditions. You can only activate 1 "Nightmare Throne" per turn.
