Is this worth for Master League?

Obviously I know the higher the % the better. I also know this very highly ranked on pvpoke for master league. I usually only use my hundo’s in there though.

Will the 2% off Attack be that crucial for PVP? I plan to do more raids, but i highly doubt i’ll be getting anything better than this.

I’m currently running a Level 50 Ho-oh, Level 47 Metagross and a level 50 Shadow Dragonite.

If I were to swap out one, which would you swap for this and why?
