Select the moves your teammates use on their move screens (I make them pretty much only use attack moves, then make them do status inducing ones on bosses) and get good at changing them with the situation.
Stock up on max elixers and reviver seeds. Gobble every gummy you find.
Admit that sometimes the game just fucks you.
Anything more specific and I can help but that's the best general advice.
