2, Exile a nonland card from your hand: Put four time counters on the exiled card. If it doesn't have suspend, it gains suspend. (At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost. If it's a creature, it has haste.)

Target player takes an extra turn after this one. Shuffle Beacon of Tomorrows into its owner's library.

This creature can't be blocked. Suspend 9—2U (Rather than cast this card from your hand, you may pay 2U and exile it with nine time counters on it.

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