Thekillman wrote: The power of an Edo is proportional to the power of the caster, yet never the full original power. Since an Edo Tensei is thus weaker, their Edo Tensei would be weaker as well. By the third layer of ET, you'd have significantly reduced total power. The power of the Edo can be upgraded with Hashirama's cells, which Kabuto had ready supply of, as he showed when saving Sasuke and upgrading Madara past his prime. Many of the Edo's were more powerful than Kabuto already. And if he wanted to he could make any of the Edo that way. We don't need a third layer as I said. Thekillman wrote: Kabuto had trouble controlling all Edo Tensei at first. When he absorbed Anko's chakra he had enough strength to control them all at nearly-full potential. But if he has to puppet Edo Tensei puppeting Edo Tensei, i don't see why his grip would undergo the same degradation as the power of edo tensei. Speculation. You're arguing that the second of your speculations should proceed along the same lines as your other speculation. Meanwhile, first speculation is highly doubtful as I've indicated above.

Kabuto only had trouble controlling them when their personalities weren't erased. Once he did there was no "them" to have trouble controlling. In any case, the fuda tag seems to be a separate issue from the actual Edo Tensei. It hasn't shown any type of degradation as you claim, but has shown a definitive upgrade with Hashi's cells.
