Aeon Chronicler's power and toughness are each equal to the number of cards in your hand.
Suspend X—. X can't be 0. (Rather than cast this card from your hand, you may pay and exile it with X time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)
Whenever a time counter is removed from Aeon Chronicler while it's exiled, draw a card.
