Notes
Vault entries gain a personal note when you add this card to your binder — pull location, sleeve type, trade history. Sign in to start tracking.
Compare the revealed cards to the creature as it last existed before it died, not to the creature card as it exists in its owner's graveyard, to determine which one you put into your hand.

If you don't reveal a creature card that shares a type with the creature that died, you'll just reveal and randomize your library.
