Not sure if i can help much, since I have 300k power and a 100k po1 unit, but i beat it with angel, edo hiruzen, wind blade asuma, and earth main. Basically nukeing as many ninjas including ay the first round with a maxed chakra angel and edo hiruzen mystery, then cleaning the rest in the following rounds. Ay never even got the chance to attack. Things to note, all my units have above 10k initiative, with po1 over 20k.
