A worthwhile permutation on deck building relying on stratified layering of chess mechanics with increasing difficulty puzzle levels to manage progression. Once you beat the game, the real limitations of how much content there is in the game becomes extremely apparent but until that point, it's an extremely engaging little chess mixup. If they added even 10 or more new cards and mix ups, or changed terrain options or vassal armies, really any added content, this could easily become a roguelike to class amongst the best.
