I will soon start playing in a game of Final Fantasy Returners 3.0 and wanted to get a heads up of any infinites, cheesy, overpowered tactics/combos/builds and what not if they even exist. I've read that they do but the person didn't mention anything about why/how.

Normally I wouldn't just ask for something like this but I don't really have a lot of time to look through it all at the moment, so all help is appreciated!
