Hmm For my oppinion Butterfly is the worst Formation I played using it and lost every game I use this formation and the idea of playing Dmr/Dml to mark Aml/Amr isn't a good idea people have to understand that Aml/R is a very attacking Position while Dmr/L is not a good deffending Position to mark an Aml/R you need to have DL/r and with Blue arrows and Also if Your Dml/r is not faster than your opponents Aml/r you will just watch your game conceding Goals coze a tortoise can't catch a Hare
I Repeat Butterfly Formation is Useless against Formations with AM
