SolForge is a trading card game that would be tough to make in real life. A bit like Scrolls, it uses counters (you increase and decrease stats permanently quite often in this game, compared to Magic: The Gathering where creatures don't keep their life totals dynamic every turn) and a grid-like playing field. There's an interesting level-up system where cards you play can come back as leveled-up versions of themselves after a few turn, making you pick the cards you want to evolve over the ones that are useful right then. Ultimately, I find it light in content and without reasons to play it before future updates.
Card Hunter is a browser-based board game with CCG and RPG elements. You control a part of three little figurines and work your way through a campaign of battles, defeating monsters, getting loot and experience and doing it all over again. I loved it enough to keep playing for a good while, but frustrating battles, low speed of character progression and strange business models make me doubt I'll play it much longer.
Scrolls is a collectible card game that follows the line of Magic The Gathering an mixes it a bit with figurine-based games to create an easy to understand blend of strategy and luck. It's interesting and some of the mechanics are changes that I like about the TCG genre but after playing it a bunch, I can't say I'm interested to play much more.
