Pringles Guy

When Pringles Guy enters the battlefield, reveal
the top card of your deck. If the bend of the card
forms an arc with interior angle greater than 30 degrees, you may cast that card without paying
its mana cost, or put it into play if it is a land. Otherwise, put the card into your graveyard.
Repeat this process until there are no cards
remaining in your library.
Once you pop, you can't stop.
