Hit the Mother Lode

Discover 10. If the discovered card's mana value is less than 10 , create a number
of tapped Treasure tokens equal to the difference. (To discover 10 , exile cards
from the top of your library until you exile a nonland card with mana value 10 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.)
