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 !
