Discover the Impossible
Instant
Look at the top five cards of your library. Exile one of them face down and put the rest on the bottom of your library in a random order. You may cast the exiled card without paying its mana cost if it's an instant spell with mana value 2 or less. If you don't, put that card into your hand.

You may cast the card you exile with Discover the Impossible as long as the resulting spell is an instant spell with mana value 2 or less, even if the card you exiled doesn't match that criteria. This may happen if you exile a split card, a modal double-faced card, an adventurer card, or similar.
