Each eye is a minute of Izanagi. That's 10 eyes so 10 minutes. Danzo can easily kill off Chiyo with his Futon's since there's no way she's avoiding them with her movement speed. So a 1v1 situation is going to be gg since Sasori's most lethal tool, poison, is useless. He just needs to appear behind Satori and smash up his heart with Futon if Satori uses ISW or large IS variants that create smoke clouds (he sees his heart via Sharingan). Also, Sharingan will read all of the IS and puppets so he won't be dying every time from IS, not to mention a large Futon blows away the IS as a counter attack.
What large fuuton are you talking about? Pretty sure he's only used fuuton blades as the offensive, also if Chiyo dies Sasori can still summon her puppets, and use them to a decent extent and Chiyo's suction puppet could be used quite well to alter the direction of Danzo's pointless fuutons (similar to Baku). Do you have proof that Izanagi can simply spawn the user wherever he pleases?
He has ten minutes but despite KG's arguing I don't recall him actually showing that he can close and open the eyes to make it last for a duration. Danzo has nothing to Kill Sasori with here so its pointless.
I will say Sharingan makes traversing the IS easier but if Sasori brings everything out (IS, 100 Puppets, Chiyo's, Himself) at once its going to be hard to keep track of it all.
