please help with this strange formation!

i have a match today in league against this formation :

DR-DC-DC-DL

DMR---------

-MC-MC-MC-

---ST-ST---


i take this like 5-3-2 and i thinking to use this formation :

——–ST——ST———
————AMC————-
ML———MC————MR
————DMC—————
——-DC–DC–DC————-

Thank you!

just a suggestion :use 4-1-3W-2 or mirror his formation use 4-1-3-1-1 with your amr or put your amc on the right side (not amr position)
