Indulged Darklord X DARK Level 4 [ Fairy / Effect ] ATK 1600 DEF 0 If this card is Normal or Special Summoned: You can take 2 "Darklord" monsters from your hand or Deck with different Levels, except "Indulged Darklord", Special Summon 1 of them to your opponent's field in Defense Position and add the other to your hand, also you cannot activate monster effects for the rest of this turn, except Fairy monsters
