This card game looks fun,but you need 50 more cards and actual game rules.Those cards aren't enough for a fully functional Bitcoin card game.Perhaps someone will create a Bitcoin monopoly game or a card game with rules that are different than the Hearthstone rules.It would be great,if there's an online version of the game,which is combined with a faucer/prize pool,so the player,who wins a tournament against other players,will get a BTC prize.

IF Blizzard is reading this they might just do it since they own the right to Hearthstone
