I don't really like this idea, because you said ANYTHING. Anything could be literally anything, from dorm upgrade, to being a tester, to mod, to admin, to OWNER even. (Yes I exaggerated) Make them instead be like Chucky Cheese's tickets, able to get certain rewards depending on the number you have. Like DP jackpots or certain privelages, or a chance to get into the White Dorm (Chance meaning you have to beat a current member in two matches out of three. Yes I mean matches, so there will be at least 4 and up to 9 total duels)
