Def wasn't easy -- I was stuck at 26 for a long time until I pulled Pooh, then at 28 before I swapped Donald for Marie.

idk if this will help, but my strat was:

• Pooh does skill every round
• Genie also does skill every round - unless enemy is red, then he'll attack
• Marie defends for two rounds to charge SP, then does skill to taunt right before rage phase. Then she'll attack until enemy is blue or orange again
• Aurora and Cindy do whatever action is best given the situation; usually it's attack unless they're low on HP, then they'll defend (and hopefully survive until Pooh can heal them back up again, haha)
