I'm having a blast with Solitairica, which has been on Steam since May, but just recently came out on iOS.
Think Fairway Solitaire where the cards represent enemy HP and enemies have a power deck which gets additional cards from random modifiers ala Diablo (e.g. Grizzled Sealypup Winter Bureaucrat where Sealypup is the base creature "this seal clubs back" and the other modifiers do things like freeze cards, give them beards (don't ask me) and give the enemy cards that increase the cost of your powers). Each time you flip over a starter card from your deck, the enemy flips a power card (some of these activate immediately and some have a timer, in which case each draw you make reduces the timer until the card activates).
There are multiple classes. Each game has 18 fights leading up to the boss. Not exactly a rogue like, but there is some randomness in monster order and modifiers. Death means starting over, but you can buy an item to escape death. There is also some progression in the form of class unlocks and upgrades for each class. These are purchased with currency awarded after each game based on how far you got. I've beaten the game with two classes and failed miserably with two more (six total, each of which is a combination of two of: strength, agility, willpower, and defense)
It's got an oddball quirkiness to it (see above) with nice presentation. It's fairly challenging, and has that roguelike quality where you can be going along incredibly well then come to a crashing halt. Definitely recommended for hardcore casuals who like the idea of a more deadly version of fairway golf.
