Its better to be lucky than good, and hedging that you can cast it from exile is the kind of bet I am interested in
Firstly, you dont actually remove the card from your opponents hand, so it can still be used in a few ways - a Troll of Khazad-dm for finding a land, for example, or even casting for an alternate cost like Evoke on Fury or Dash on Ragavan, Nimble Pilferer
In fact, the resulting creature looks exactly like the face-down creature you get if you cast a creature spell using disguise
Jolteon V Jolteon VMAX might seem like the star of the show, but Jolteon V (Jolteon Vmax Box) can definitely get the party started
By the time the set actually comes out, I wouldn't be surprised if Forge has 150 or more of its cards standing by
