I have a made a lot of changes in the game.
The first is the most important: a player will receive 13 cards in the first dealing. This change is based on your feedback and I like the result much.
The second: I have changed the reward in Duels. Now you can get mythic cards there. Note that mythic cards have no race and can be used in any deck.
The third: I have not finished it yet but it will be available on Sunday. I have changed the Sunday challenge. The Gold Rush will bring you a lot of gold now :)
The fourth: I have rebalanced the undead. Necromancers and skeleton have strong synergy now. Also, I am working on vampires and ghosts. In a couple of days, I will finish it.
Thank you all for your suggestion and ideas!
PS: You see an upcoming new ghost on the picture :)
