I played a few games of this new HoldemX today. There’s a site up and running now where you can create an account and play. I think the site actually just launched, with this being called the “alpha version” of the game meant to introduce it and get feedback from players.
This article on PokerNews gives a bit of background about the game and a little on how it fits into this larger vision of Alex Dreyfus and the Global Poker League. The article points out how the game combines hold’em and other card-based games like Magic: The Gathering, Hearthstone (about which I was writing a little here a while back), and Uno.
