{t}: Draw a card, then exile a card from your
hand and put a number of time counters on it
equal to its mana value. It gains "When the last
time counter is removed from this card, if it's
exiled, you may cast it without paying its mana
cost. If you cast a creature spell this way, it gains
haste until end of turn." Then remove a time
counter from each other card you own in exile.
"Do you think God stays in heaven because he too
lives in fear of what he's created?"-Dr. Romero
