Kill all puppets before you kill sasori and he won't revive =)

Take out the puppets first or take them out at the same time if there's one puppet alive he'll be able to revive indefinitely.

used kimimaro my main (MB ) and tenten mastery and kill him and his puppets all at the same time, just let kimi tank the dmg while gattering enough chakra for 3 aoe skill release.

Thanks everyone! I was so salty when he kept coming back ;-;
