Hi there,
Im not sure what summons do you have, but you can try something like this:
- Tsunade is immune to debuffs, c*e mystery every round and provides extra standard attack for herself and main.
- Kimi and Masked man can be used in round 1 to control up to 2 enemy ninjas in round 1 (Masked man has high chance of causing repulse, so you can eventually control 3rd ninja in round 1)
- P2, P3 and P4 can dodge some of incoming damage, making this team more sustainable.
- With Tsunade´ passive, this team can heal 4 times with standards (with ideal outcome, entire team gets immunity lv.2 and gets healed twice with +50% heal boost)

rest depends on match up and difference between yours and enemy´s initiative.
