One-Winged Darklord
You can only use this Skill's second effect once per Duel.
1: At the beginning of the Duel, add 1 "Darklord Contact" and 1 "Darklord Uprising" to your Deck. During this Duel, you cannot Normal or Special Summon any monsters except for "Darklord" monsters (excluding Special Summons from the Extra Deck).
2: Shuffle 1 "Capricious Darklord" or "Indulged Darklord" from your hand into the Deck, then add 1 "Indulged Darklord"or "Capricious Darklord" with a different name from the shuffled monster from your Deck to your hand. If only your opponent controls a monster, you can add 1 "Forbidden" Quick-Play Spell Card from your Deck to your hand instead.
