Discover is a keyword action introduced in The Lost Caverns of Ixalan..

Description

To Discover X means "Exile cards from the top of your library until you exile a nonland card with mana value X 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."

Discover is a revamped version of cascade with more design space. Instead of being a cast trigger, it's a keyword action that always comes with a value. To discover X, exile cards from the top of your library until you exile a nonland card with mana value X or less. To avoid whiffing on something like a counterspell, there is now a choice to cast the spell or simply put it into your hand. Then put the other exiled cards on the bottom of your library.
