I'm trying to learn how to counter formations by myself, but I'm not sure if it would work because my formation seems strange!

My opponent is using:

DL-DC-DC-DR
----DMC
-MC-MC-MC
---AMC
----ST

So for me to counter it, I need to focus my defense in the middle and attack down the flanks.
I was thinking of using:

-DC-DC-DC
--DMC-DMC-
--MC-MC-
AML---AMR
----ST

Is this a good way to counter him? or is there something better? Maybe using 1 DMC and 3 MC's instead.
