Zoe, The Aspect of Twilight

Flying.

When Zoe damages a player search your library and graveyard for a card with mana cost 3 or less and a celestial subtype, add it to your hand, and shuffle.

Level up (When you play 10 unique cards grant Zoe +1/+1 and "Zoe's ability is no longer limited to cards with mana cost 3 or less.")
