Rating issues
During battles, cards with characters on it oppose each other. One card smashes into the other one, causing it to break. Players can also use spells to attack creatures on the game board: the creatures flinch slightly, and disappear if defeated. Some cut scenes show soldiers and guards being struck down, or lying dead on the ground, but there are no visible injuries or blood effects.
Other issues
Some card and character designs are slightly sinister and may be disturbing to young children.
