Playdek, makers of the fine Ascension iOS app game has finally released it's Nightfall Deckbuilding game in iOS as well! For $4.99, the original set of cards are all yours, in a nice, slick, well presented application!
So far, after a few games, the artowork pops, the animation is smooth, and the tutorial is very well laid out. As I imagined too, the chain and kicker effects are SO much easier to see and plan in this format.
Let us know if you get it and what you think!
