Today have cup rematch and need help to beat 4-4-2. Need win Lose 2-4

In the first match use this tactic:

----ST----ST----
--ML--MC--MC--MR
------DMC-------
----DC--DC--DC--

now I'm thinking about using a 5-2-1-2 OR butterfly (but this last tactic not to give instructions)

They recommend me to use?
