How about a token shop? Tokens are really hard to get in this camp.
Every challenge will give you a number of token points. Better you do in the challenge, the more token points you get. People who DNP get 0 token points, and people up for resign ups have their token points reset.

Depending on rarity, some tokens cost more token points then others. This way, it's not the easiest thing to get a TT. The amount of TPs you can get maximum in a challenge and prices are up to you. It's just there a lot of people without tokens, and I think there could be a somewhat easier way to get tokens then having to be either really smart and old or really lucky in order to get tokens.

What about a creativity challenge? You have to describe a house. How many rooms are in it, how many bathrooms, how many kitchen and others. XD

also if the token shop is a thing, make the opposite token cost the most
