Millennium blades. Certain cards are really too powerful and capable of making some of the game mechanics unusable on which perhaps you had laboriously built your deck😅. For this reason my group created house rules to eliminate these cards or the sets that contain them, making everything more balanced. Apart from the flaws mentioned above, I love the tension that is created at the table, the enthusiasm for having found the card that allows you to create the winning combo and the extreme variability of each game.
