You can use Wolf Berry in your Kerria+Saffron+Pinladies team to get Negate damages and survive a bit more. And maybe Easter Cactus to revive once if someone die.
Then, I guess you should try to move girls from a team to another until you found the best configuration. And try to send your team to death in a different order.
Another advice, forgot about Counter this time. Counter team don't survive more than 2 or 3 turns, even with Saffron and Easter Cactus. Espacially against thoses Butterflies.
