GA matching gave me the idea of getting to make our own wager battles with our own rewards.
you post your own team
you select a type of team to beat it (pure phoenix, NS, whatever. All toons simply need the tag you pick.
You pick a wager. Crystals, credits, and an amount.
Then your wager gets posted to a wager list that has been matched using the same match mechanic as GA matching.
They win. They get the wager. They lose, you get it. House takes 10%. If the wager isn't taken in a week it is deleted.
