Priority Boarding

Enchantment

Whenever you roll a die, you may reveal the top card of your library. Do this only once each turn. Whenever you reveal a card with mana value less than the result this way, you may exile it. If you do, you may play it this turn.

The Astrotorium's express lane is practically its own ride.
