], something which would've clearly improved Edo Nagato's chances of killing the Jinchūriki (if he could follow up with a Chou Shinra Tensei).
You seem to think that the Edo Tensei user always has full knowledge on his summons.
However, we've seen that Kabuto was unaware of Itachi and his link with Kotoamatsukami, something which eventually led to his downfall.
We've also seen that Kabuto had no idea that Madara could defy the Edo Tensei with his knowledge of its seals, again, showing that the summoner isn't necessarily omniscient.
And of course, there's the page which I already posted showing that there was some hesitance on Kabuto's part when trying to recall what Nagato was actually capable of (in terms of jutsu).
