Valve has announced Artifact, a Dota 2 online card game, during The International 7 that's being held in Seattle.
The card game is planned for a 2018 release. It will feature known characters in Dota 2 and will also feature lanes. Meaning, Artifact will be the card version of the MOBA.
According to TI7 host Sean "Day[9[" Plott, the game will feature a variety of Dota 2 features.
"Anything you see in Dota, it's here." said Plott.
In Artifact, players will be playing this game as if they are controlling all five heroes in a Dota 2 team. You maintain all five of the heroes and the game will feature a three-board format, representing Dota 2's "lanes". Creeps will also be going through each of the lane, just like the MOBA game.
It will be interesting to see how it plays out visually and if it will be easy to manage, gameplay-wise. We'll hear more about it after TI7's conclusion.
This is no surprise since a handful of good online card games have surfaced thanks to the big success of Blizzard's Hearthstone. Bethesda released their own online card game called Elder Scrolls Legends and CD Projekt RED's Gwent card game is currently in public beta. Shadowverse and more card games are now out in the wild to take some of the online card game pie, so it only makes sense that a big company like Valve would take a shot at this growing competitive genre.
