The first thing Minato will do is create 1 Kage Bunshin and it will prepare the marked kunai's around the battlefield. In base alone, Minato could mark a battlefield [

]. All of those instances happened under 1 chapter and by Base Minato's foot-speed. This Minato is significantly boosted with Kurama's Chakra, which we have seen the difference in speed between Base/SM Naruto to KCM Naruto. Minato's Bunshin will have few seconds to mark the battlefield with kunai's in order to proficiently counter every attack of Sasuke. And To be honest with you, Minato doesn't need any marked kunai's, because firstly Sasuke has no massive AOE technique. And secondly nothing which Minato is unable to react to and dodge without Hiraishin.
1). He can react to the likes of full-speed Ay. [

All of EMS Sasuke's attacks have no chance of hitting Minato, when the latter has the reaction and reflexes to counter them without any teleportation now he has KCM instead. But whatever, I'll keep the marked kunai for insurance.
