There is nothing you could do against Mylor in that ruleset it is annoying when that happens but it is part of the game.
It doesn't look easy to fight with GF cards, am sure your performance would have been better fighting other suitable frays but, understandably, you are doing this for the guild since most shy away from only GF fray.
It's not easy but that works out better for our guild rank placements. The last few gold brawls have been really rough.
