Heaven's Descent

Split Second
Exile all creatures and planeswalkers. Players
can't cast creature or planeswalker spells until the
start of your next turn. Instant and sorcery cards
in your graveyard have Flashback equal to their
mana cost until the end of your next turn, if the
Miracle cost for this spell was not paid those
spells cost {2} less to cast. Exile Heaven's Descent.
