Prestidigitation Show

Daredevil {x}{b/r}(You can cast this spell for
its daredevil cost if you didn't lose life this turn.)
Target opponent shuffles its library, then exiles
X cards from the top of its library. Choose a card
between them. Then shuffle the exiled cards
into a pile. Reveal the top card of the pile.
If it is the chosen card, you can cast it without
paying its mana cost, if it is not the chosen card,
each player loses life equal to it's converted mana
cost.
