Oracle Text
Whenever you cast a signed spell or play a signed land, copy it. (A signed card is a card signed by its artist, designer, or someone else it's strongly associated with.)
Discard a signed card: Destroy target creature with a name that has a five or fewer letter length difference from the person who signed the discarded card.
