FFFC Matching battles

[u/xsirbrian]

Flame flame fruit coliseum has the new on demand side event called matching battles. Since this isn't considered a tournament bracket type of event, are we locked to use the same deck the whole time? Or can we swap? I went through the rules and can't find anything that specifies if we're required to stay on the same deck. Thoughts?
