During their main phase any player may pay {X}, if they do they gain (a^b)*(c^d)*(e^f) and you gain a^b+c^d+e^f life, where a, b, c, d, e, and f are the amount of {G} {U} {W} {B} {R} and {C} spent to pay {X} assigned as the player paying the mana chooses. {flavor} Now remember, in Magic The Gathering all Numbers must be integers, and calculable, if the result is not an integer or if you can not calculate it, then the value of it becomes 0.
