Here's to the hope that Nightfall is stronger in the deck building, collection and persistence areas than Playdeck's previous Ascension. Stuff like an online card market and deck building progression elements, Urban Rivals style, can help build a community and turn an iOS TCG into a a semi-MMO, and offer heaps and mounds of additional incentive to play...
Nightfall and Ascension are similar in scope. In the hobby boardgame market, "deck building" refers to any game the borrows its inspiration from Dominion in that you are creating your deck on the fly during game play, rather than pre-constructing your own deck prior to the beginning of the game. Nightfall comes closer to Magic: the Gathering than Ascension did in that you have card effects where you get to choose specific targets and you have to choose a target opponent when your minions attack.
This genre of game was created as a direct counter to the CCGs that you list, so that players didn't feel trapped in an endless cycle of having to purchase new product in order to remain competitive.
Our next major release, Summoner Wars, is probably more in line with the type of game you're looking for, although it will come closer to the "living card game" model, in that you will have multiple different purchase options to unlock additional content, but you will always know exactly which cards will be contained in that pack.
