I absolutely HATE floor 20 Jane Doe

I'm completely stuck at floor 20 on the simulated battle trial and my team is composed of Miyabi, Jane, and Yao. All of them are at max level even their skills and everything. It might be a skill issue on my part because my best was below 20% HP and it has been consistent for the past 3 hours. Can someone tell me at least the best team I need to get from floor 15 to 20 and beat Jane?
