How to beat 3W-2-3N-2

Hi guys. I need to win this game to take 1st place in da league.
He is playin
DL-DC-DR
DML-DMR
MC-MC-MC
ST-ST
I dont see this formation in table. Never saw that tactic before. He is slightly better then me, but I play at home. Any suggestion?! I thought about 4-1-2-1-2 Narrow Diamond or 4-1-3W-1-1 is it good idea?

Since you'll be playing home, I think 4-1-2-1-2 ND, Hard Attacking, Through the middle, Counter Off, Mixed Passing.
