Shameless advertisement for a game released under the brand of the company I work for (actually not developed by us, but my CTO is the game designer and he allied himself with a know Magic artist and a Danish game development company):
http://www.soulsparkgame.com/It's a card game in the same genre as Hearthstone, but plays out realtime rather than turn based. Less about luck/building decks, more about quick thinking and countering the opponent (which for the moment is the AI only
).
Sadly it's only for iPhone/iPad so far, but here's the direct link to iTunes (actually I have no idea if you can download it outside of Denmark):
