Snikelfritz, the Dreamer

Flying
The first time you cast a noncreature spell
each turn, you may roll a d6 then discover X, where X is the result. (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.)
