YMMV: Mage Knight
- Goddamn Bats: There are a few enemies in the game who are both Armored (non-Elemental attacks are only half effective against them) and have an Elemental attack (Blocks that don't belong to the opposite Element are halved). If you only have non-Elemental cards in your hand, prepare to waste a ton of them and take some Wounds to get rid of the enemy.
- Scrappy Mechanic: The rules esplicitly tell that you can go back and redo any action, provided that you didn't reveal any previously unknown information (so there's no avoiding fighting a monster token you just flipped, for example). While this is great for new players, who cannot possibly know which moves and card combinations are optimal and which ones are not, it can be painful for everyone else at the table, who is forced to wait while the player continues going back and forth, considering every possible option.
