Titan's Crossing

When Titan's Crossing enters the battlefield,
look at the top five cards of your library. You
may reveal a creature card from among them and
exile it with four summoning counters on it. Put
the rest in your graveyard.
{t}, Remove a summoning counter from a card
you own in exile: Add {c}{c}. When the last
summoning counter is removed, put the exiled
card into your hand.
