Nope, definitely doesn't work at 52k power because or you won't be able to kill danzo in wave 3 before wave 3 10th round is reached or you simply wont have enough power to one shot itachi in wave 4 regardless the stacks you added of reserve seal. At 52k power, honestly speaking, i think you just flat out get wiped out at the end of wave 1 without autoshields like iruka's or ao's ones.
