Heres a few teams, they mostly get better as they go down, just try to use whatever you can based on the ninjas you own, the result your looking for is to buff your Fire Main as much as possible.

1. When using Anko, don't recast her barrier as you will lose the buff, the idea is to overbuff your Fire Main.

2. Use the Coin Boost x3 and Coupon Boost x3 before it starts at top of screen.

3. If you already have x3 Coupon boost, you can simply retreat from the Ambush fight with Masked Man and continue with tails, Fighting him grants 10% damage from the coupon boost so no need to do it if you already bought x3.

4. In the 4th round, try to retreat after your 4th person has attacked, that way you skip the animation of the tails killing you with his beam.

5. If you feel you die too fast you can switch the 4th passive out on your tree for your clone as it can soak some damage up.

6. Jonin medal for 1888 Ingots and lasts 180 days($40) will grant another 15% damage, I think thats how much it gives.

7. You can reposition people base on what tactic you use, but try to only have one person at front as tail sweeps hittiing multiple targets.
