Mega Aggron! Finally, it’s almost okay to use it? The move set keeps it a bit out of the spotlight for PvE raids, but it’s a Mega, and Mega have bonuses outside of being a useful pokemon. So get your candy, and find a shiny!
You’ll rely on some heavy fighters for this one, the easiest option is good old machamp, and a shadow one is even better. If you are lucky enough to have a Terrakion with Sacred Sword, it’s new fighting fast move vaults it to the top!
