I disagree,
Enton arrows are useless to gaara's sand,as gaara's sand is immunt to the blackflames effect,also chakra rods stopped them easily. That image you showed was enton slicing a naked juubi clone,that was just enton vs bare skin,hardly a feat. When enton came against an actual solid object in the form of a chakra rod,it got halted,gaara played catch with sasuke's black flames already
onoki himself needs to stay stationary,if he is on Ay's back,he isnt the one moving,so he is actually stationary,as such sasuke gets murked.This only lets them live for a moment longer. In order to use Jinton, Ohnoki needs to stay stationary. If he is on Ei's back and Ei will be running around, this isn't possible. More so, the amount of time Ei can keep V2 up is a extremely short period of time so once V2 cannot be used anymore, Sasuke's Amaterasu will hit them.
Gaara's sand cannot block Enton Arrows. Due to the Enton properties, it would pierce throught a solid object without any problem at all [You must be registered for see links], therefore a defense such as Gaara's sand won't work.
