What "Edo techs" did he get, would you kindly remind me?So your talking about Edo Nagato? Thats not really Nagato he's also powered up from the Edo tech..Prime Nagato before he was sick was before he had Gedo Mazo and im sorry i just dont think he could beat Minito at that stage.He Got sick because of the power he accepted, but there are also drawbacks to that power. Edo Nagato I dont count because thats also using Kabuto's power and some of Nagato's.
Also, when he retaliated against Danzo+Hanzo's forces, he wasn't sick but he used Gedo Mazo.
