you should focus on playing in the wings, because most of his players are in the middle
i would play like that:

dc dc dc
dmc
mr mc mc ml
st st

put red arrows on MR and ML
if you want you can put blue arrow on DMC, but that depends on how strong is your opponent and how strong your defense is
play on both flanks, you can counter attack if you want, as your opponent doesn't have a DMC
