It seems like a take on the 4-2-2-2 hexagon. I have used 4-3w-1-2 to counter this, with down arrows on my ML and MR so they help defend the AML and AMR.

Personally, I'd avoid using a DMC as it seems a bit wasted with no AMC, but others may think differently. And since they have no DMC, using an AMC gives you an advantage. 4v4 in the midfield, so it may depend on quality of players. How does their quality compare to yours?

Good luck with your matchup!
