I'm on World 10-2 and it is absolutely impossible to pass. I've tried all different combinations and even went to research how others did it. Seems that just short of getting every single character that has a 1 in a billion chance of getting at full strength, you won't pass it. Please look into world 10 since the monsters are insanely hard like 6 levels above and nothing kills them. Add the revive limit and it makes it impossible. Devs please fix this. Make it more doable for the entire world.
