It is free to play, however it only comes with one PvE campaign. Additional ones cost about two bucks. You start with a basic color deck of 40 cards, and can buy booster packs of 14 cards for about two bucks. You can do random pug games, or several different types of tournaments they have.
I'd say give it a try if it sounds interesting. It doesn't look all that impressive up front, but it can be really enjoyable.

If you do decide to play let me know I can get you a free booster pack or two. Vin~ fucked around with this message on 11-17-2011 at 02:59 PM.
--which as a side note the new cards set is rather fun, the whole gothic horror them is nice plus I have a made a workable Parallel Live Zombie deck, nothing better than puting out 26 zombies one turn when your opponent has burned up all his answers
