The best PvP board game I've played on mobile, with a few things I don't like. The graphics and game play are great, balanced and not too pay to win with optional only ads for speeding up chests. You can unlock cards to put in your deck from getting achievements, however, some of these achievements, like buy 3 skins, lock cards behind a pay wall. You can earn premium currency but I prefer to buy card chests instead of cosmetics with my hard earned gems. Guilds needs more features, but solid base
