u/O_o-Inconceivable

If anyone is interested, I created a Git repo that has code to get Elements the Game arena "working" in your Flashpoint instance. It progresses as you play in the arena and you can load your own decks into the arena as well.

It works in Flashpoint 14.0.3 Infinity ("Kingfisher").
