>>49018892the best strategy i found for the final boss in gale is to bring mostly shadow pokemon of your own so you can resist the attacks, and use shadow half a few times to easily weaken his team
oh and also leaving a space in your party for lugia as that can easily tank pretty much everything he throws at you, one of the few times i legit use a master ball because fighting that thing normally is a pain in the ass
also bring a shitton of healing items
