Open beta just started for a new online MTG game called "Arena". They followed the Hearthstone format pretty closely, but with MTG rules and all of the current standard card sets.

I played some last night and will be again tonight. The gameplay is very smooth, and the options for draft are payable by either gems, which are purchased for real money, or gold which is earned through quests, just like in Hearthstone. The drafts follow MTG booster draft format, which I have always liked much better than Hearthstone's simpler arena format.

I forgot how much i missed playing this game, and this is the best online version of it to come out since MTG Online, which didnt really have any free to play options or ways to earn cards.

I hope they eventually incorporate some of the multiplayer game formats, like castle, emperor, etc, because that was another thing I was hoping would eventually be in Hearthstone, but I am sure they will never do.
