As part of my project to flood Agora with Canada references, I'm considering a contest along these lines, though I'm still not sure how Power-1 Dances would be obtained. I was thinking 2 Power-N dances could be converted to 1 Power-(N+1) Dance, Dances of Power-4 or greater are Powerful Dances, and Dances can be redeemed for 2.1^(P-1) where P is the Power of the Dance.
