Three Minutes Between Life and Death

The Iron Sand fills the cavern. Sasori wields the Third Kazekage puppet's magnetic kekkei genkai as a storm of bladed sand, and Sakura and Chiyo survive on three-minute windows — the time an antidote buys against Sasori's poison before the next dose. The episode is the duel at its most lethal: Chiyo's ten-puppet mastery guiding Sakura's fists through a minefield, grandmother and apprentice fighting a man who feels nothing, against weapons made from the dead. Every exchange runs on the clock the poison sets.
