Just figured I'd jot down some game related information for the "Crystal Heroes" Re-boot!
The deck is comprised of ten (10) cards:
"x": Warlord - multiplication = 2 x 3 = 6 (1x)
"|": Thief, Ranger, Bard - special or = 5 | 3 = 10 (2x)
"-": Mage, Cleric - subtraction = 6 - 2 = 4 (3x)
"+": Fighter - addition = 4 + 3 = 7 (4x)
Those are only the classes and operators. The one worth noting is the "special or": what it means is "of two (2) numbers, choose the highest and add them together." So 5 | 3 = 5 + 5 = 10.
