Artifact is to release on November 28th. It is a Dota inspired card game created by Valve in conjunction with Richard Garfield, creator of Magic. The game is played across three boards(lanes) similar to Dota, in which you can destroy the enemies 40 health tower in 2 of the lanes to win, or you can just go hard and kill their tower in one lane, and then kill the 80 health ancient that spawns in place of the tower. The game features hero cards with signature spells and cards that if killed will sit out a round and then rejoin the game, that can also have items equipped that are purchased with gold that is gained from killing the enemy's creeps and heroes.
Here is a well made video that explains in good detail how to play:
It is still in closed beta, but to help them better understand which cards are potentially over or under powered, they have been having tournaments for money amongst the closed beta players. One of those tournaments is occuring in an hour from this post on twitch.tv/btsartifact as well as steam.tv and will have casters/commentators, etc.
