Tales and Scares

Creatures you control gain Haste, Menace, Trample, Lifelink, and Vigilance until end of turn.
At the end of this turn you may exile cards
from the top of your library up to equal the
number of creatures you control that died
this turn, you may play any of those cards as
if they required mana of any color to cast for
as long as they remain exiled.
