Aeon Chronicler

Creature - Avatar */*, 3UU (5)
Aeon Chronicler's power and toughness are each equal to the number of cards in your hand.

Suspend X-{X}{3}{U}. X can't be 0. (Rather than cast this card from your hand, you may pay {X}{3}{U} 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.¹
Illus. Dan Dos Santos

Gatherer Card Rulings [Nov 2009]

• 2/1/2007: Both instances of X in the suspend ability are the same. You determine the value of X as you suspend the card from your hand. The value you choose must be at least 1.
• 2/1/2007: If this is suspended, then when the last time counter is removed from it, both its triggered ability and the "play this card" part of the suspend ability will trigger. They can be put on the stack in either order.
