Archlord Kristya (SOVR-EN096) - Stardust Overdrive 1st Edition

If you have exactly 4 Fairy monsters in your GY, you can Special Summon this card (from your hand). If Summoned this way: Target 1 Fairy monster in your GY; add that target to your hand. Neither player can Special Summon monsters. If this face-up card would be sent from the field to the GY, place it on top of the Deck, instead.
