It's simply a rearranged of 4-5-1, with a bit more defense thanks to the 2 DMCs (I bet he even put red arrows on them).
So best thing to do is use a variation of 3-5-2. Something like this should do :
-------ST--ST-------
AML-------------AMR
-----MC-MC-MC-----
--------------------
-----DC-DC-DC------
Good luck !
