Chronomantic Escape
Sorcery
(CMC 6)
Until your next turn, creatures can't attack you. Exile Chronomantic Escape with three time counters on it.
Suspend 3-- (Rather than cast this card from your hand, you may pay 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.)
