my prediction is that the trump card will belong to Gray but it will be prevented by Irene doing some big AOE like mass petrification to knock everyone out so she can get Mavis unimpeded; but of course Erza will brake free somehow (likely her fake eye coming in handy again) and they will finally have their confrontation.
