Instant - Arcane, 5U (6) 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 into play, then shuffles his or her library. Splice onto Arcane {2}{U}{U}1

4/1/2005: When Reweave resolves it uses the type(s) that the permanent had right before it was sacrificed
11/1/2005: The player reveals cards only if the targeted permanent gets sacrificed.
4/1/2008: With the introduction of the Tribal type it became possible for an instant or sorcery card to share a type with the sacrificed permanent (ie, a Tribal Instant card shares a type with a Tribal Enchantment card). Reweave has received errata so that the effect looks for a *permanent* card that shares a type with the sacrificed permanent. A permanent card is a card that could be put into play, which is any card that isn't an Instant or Sorcery.
