Suspend 9—2U (Rather than cast this card from your hand, you may pay 2U and exile it with nine time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost. It has haste.)

Whenever an opponent casts a spell, if this card is suspended, remove a time counter from it.
