- 18 February 2022You 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.
