Hi, i am going to play against a 3w-2(dmc) -3w-2 team on monday for the semi-final's cup. I saw in the table that 3w-5-2 can counter this formation. However my opponent is a lot stronger than me. He is 120% whereas i am just 100%. Do I have a chance ? And does the 3w-5-2 stay a good formation against this stronger team ? Moreover I haven't any idee for the orders.
Thank you very much.

P.S. Sorry for my english, I'm french.
