Ma'at (Secret Rare)

Cannot be Normal Summoned or Set. Must be Special Summoned (from your hand) by sending 1 face-up LIGHT Dragon-Type and 1 face-up LIGHT Fairy-Type monster you control to the Graveyard, and cannot be Special Summoned by other ways. Once per turn: You can declare 3 card names; reveal the top 3 cards of your Deck, add the declared card(s) to your hand, and send the other cards revealed by this effect to the Graveyard, and this card's ATK and DEF becomes the number of cards you added to your hand by this effect × 1000.
