I usually like card games, but I miss opportunity to cast more cards at once. Also who wins depends highly on who starts, because first player has one more card at the board each turn and deal damage first. And I was not able to read full descriptions of cards. But I get, that making card games is really hard and create well balanced game is even harder, so good job. Fits the theme very well, because when you have a chance of putting more knights at once you have unstoppable army.
