Hey ;)
Here some informations i realize about M5K:

- It remove the double attack buff from Bee's mystery BUT he do not affect the interruption immunity's buff from the same mystery

- It don't remove atk and combo buff from minato's chase

- BUT it remove the kurama naruto's bufffrom his chase (+80% combo)

An other thing about m5k:

He is not a konoha ninja, so Chiriku's buff or madara founder's buff do not work on M5k, but Madara can't remove this buff
