4WW
Sorcery
Until your next turn, creatures can't attack you. Exile Chronomantic Escape with three time counters on it.
Suspend 3—2W (Rather than cast this card from your hand, you may pay 2W and exile it with three 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.)
