Seriously, why all the hype?
Frankly, I don't see why this game gets so many attentions. There are tons of TCGs out there, and Artifact is not so different than others. Just adding colors to the cards is not the answer, and creating two more lanes certainly is a bad move. That doesn't decide how deep the game is. It just confuses players by adding unnecessary complexity. To be clear, I am not a fan of Hearthstone, but it's apparent that Blizzard is already taking up most of the digital TCG market. By the looks of it, Valve's going to have a hard time dethroning the champion, imho.
