Reweave

Target permanent's controller sacrifices it. If he or she does, that player reveals cards from the top of his or her library until he or she reveals a permanent card that shares a card type with the sacrificed permanent, puts that card onto the battlefield, then shuffles his or her library.

Splice onto Arcane (As you cast an Arcane spell, you may reveal this card from your hand and pay its splice cost. If you do, add this card's effects to that spell.)
