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