Azcanta Serpent

Azcanta Serpent has hexproof as long as there are
seven or more cards in your graveyard.
When Azcanta Serpent enters the battlefield,
search your library for up to three noncreature
nonland cards with different names and reveal
them. Put those cards into your hand, then
shuffle your library.
