Counter target artifact or creature spell. Discover X, where X is that spell's mana value. (Exile cards from the top of your library until you exile a nonland card with that mana value or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)

If you can't cast the discovered card (perhaps because there are no legal targets for the spell), you'll put it into your hand.

Some spells and abilities that cause you to discover may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve and you won't discover.

When you discover, you must exile cards. The only optional part of the ability is whether you cast the exiled card or put it into your hand.
