I think your game could be much more engaging if you focus more on deck building and cards balancing. Current set of cards seems too random. Also the starting deck is too big. Adding only one card after each battle makes it boring pretty quickly. It's hard to build the deck around any strategy.
Thanks for playing my game! I kinda got bored working on this project, so it's pretty much abandoned at this point. Your criticism is spot on. The goal was to make the game more strategic with different deck building mechanics and multiple starting classes that would have their own decks. For example you could start as a Dwarf and beat the opponent by outmining and outbuilding or you could start as Mage and have a deck full of spells etc.
