I played this last weekend, a friend brought it back from Gencon. It was quite the hit, all of my friends who demo'ed it at Gencon liked it enough to buy it.
It was not a hit with me, though. The building a card mechanic is meaningful about 20% of the time, but you have to fool with sleeving cards 100% of the time.
The push your luck mechanic is pretty nasty with how it combines with the scaling effect of deckbuilders. It's very common to get into an early game situation where it's definitely correct to push, but the upside of the bad push is exponential scaling that will cascade through the rest of the game, and the downside of the push is exponential unscaling that will cascade through the rest of the game. It's kinda like Dominion composed of nothing but kingdoms where Swindler/Swindler is the correct opening and you have to go for that even though you'll collide the Swindlers and Swindle an Estate a lot of the time and have to languish for the rest of the game in a dismal vortex.
