Probably the best strategy card game. Beautiful art, fun and unique character classes, and even free-to-play players can make a competitive deck or two. The power creep problem is real though. There's hardly any reason to use cards other than the last couple packs that have come out, and the meta is annoying as hell if you get out of the absolute beginner level of competitive play. And the open-6-packs tournaments are basically ruined if you play against any player who gets a particular card.
