Survival Stradegies

I know theres a normal stradegies topic but this is about stradegies in the survival challenges. Since its kind of hard to beat all of the challenges with everyone lets see if you guys have any ideas. Alright I have one for Sakura:when you get close enough to the enemy use the shock blossom move and then shock wavewhile the person is on the floor and then repeat until the enemy dies.

I have one for Naruto; get the unlimited chakra skill chip-you have to complete all of the missions then you buy it at the store it's 80,000 ryo- then shadow clone swarm!
