Hey Joey! Hope all is going well. I got a UU team I built for the Farewell Mega Aerodactyl video whenever you decide to record it. At first glance, the team might seem a little Mamoswine weak but between Rotom and defensive Primarina, you should be able to handle it. Feel free to change anything you'd like though, and enjoy the team if you do end up using it!
