Idea Wagers

I'm not sure if this idea has been suggested, but this is my idea.
Wagers are duels, where two players place down their bets and battle for the pot.
So I think that adding wagers in KitBrawl would be smart, because that would bring a competitive aspect to the gamemode. Adding Wagers would give people a good reason to become good at the gamemode.
What would you wager? I would love to see voting tokens being the wager currency. I think so becuase voting helps the server's popularity, and the tokens can be used in other gamemodes, such as Raid. People can get 50-100 tokens a day, and this would also give people a reason to buy a rank.
How would the wagers go down? I think that you should be able to challenge someone on the server, select an amount of voting tokens (I'm thinking 10-1000), and the kit. I would also love to see 2v2 wagers.
