*** Max pinch healing strongly recommended! Key LB for Corazon or Luffy&Ace will be helpful but is not necessary.
*** You'll need some meat orb luck in Stage 7&9 depending on your LB/supports.
*** Don't forget to switch Iva&Bon whenever necessary!!!
(Stage 6) I think it's better to stall 2 more turns so you don't waste Iva&Bon's heal (no healing during pre-emptives).
(Stage 7) Try to hit with paralyzed units in the first turn 🙂 It wasn't necessary in my case.
(Stage 9) Meat orbs pls 🙁
