Look at the top 4 cards of your deck. You may reveal a spell from among them and add it into your hand. You may also put a spell into your cemetery. Put the remaining cards on the bottom of your deck in any order.
QCan I choose not to put a spell into my hand or not to put a spell into my cemetery with this spell?
AYes. You can choose whether to perform each action.
QIf I have less than 4 cards in my deck, can I still play this spell?
AYes, you can. You would simply look at all the cards in your deck, and return any remaining cards to your deck area in any order.
QCan I look at my evolve deck with this spell?
ANo. You can only look at your main deck.
