Lyla la Magicienne, Seigneur Lumière SDDC-FR021

During your Main Phase, you can target 1 Spell/Trap Card controlled by your opponent, change that card to face-up Attack Position that you control in face-up Defense Position, and destroy the target, but until the end of your next turn, the battle position of that card cannot be changed, except with a card effect. During each of your End Phases, send the top 3 cards of your Deck to the Graveyard. You must control this card face-up to activate and resolve this effect.
