If you're still a little unsure about what's happening with Valve's Dota 2 CCG, here's six minutes of footage that probably won't help.
First announced at last year's International (to much surprise), Artifact is a CCG inspired directly by Dota 2. You get five heroes, each of which can be deployed between one of three lanes, a little like actual Dota gameplay.
Each lane has a tower, its own mana pool, and creeps for both sides. Your heroes can buy and equip items as well, just like the MOBA proper, and as a result Artifact sounds a lot more involved than your regular card game.
It's the kind of game that will probably take a few hours to really get to grips with. I don't know that I'd agree with the initial comment that it's like Hearthstone - Blizzard's CCG is much, much simpler - but the way different heroes and their colours open up various options is intriguing.

Valve recently demoed its upcoming card game Artifact at its Seattle office and the details have begun pouring in. While Valve founder Gabe Newell reportedly called Blizzard's Hearthstone the "benchmark" for online card games, Artifact sounds as though it will be very different.
