You wish to pass that exam, yall?

You are f2p and all videos on that exam make you change team or have ninjas you probably dont have?

Or just take 8 rounds and then you got nothing left to do to get 2nd wave?

Here is one simple lineup:

Kinkaku, Tenten [ gnw ], literally any main (its tested) and asuma [ wind blade] for chakra, or any other ninja you like, just asuma gives enough chakra you like

Current power: 223k, but honestly, power doesnt matter, round one goes tenten, round 2 kinkaku, round 3 again tenten etc

Its one purely f2p team, both kinkaku and tenten do dmg to all puppets, so it will take max 5 rounds to get rid of all of them, water helps with poisoning, but still works with any other main as well.

Decided to put shark bomb to finish the 2nd wave off faster and heal in cause one is dying.

That's all, hope it helps someone.
