Pokemon GO - Beldum 3 Star Max Battle Solo - NEW Gengar/Excadrill Showcase - feat. "Lick" Fast Move

Here's a tip: The reason the legacy move "Lick" is used over Hex is because of how fast Gengar gets online by using the Dynamax function.
Then again, Excadrill's Mud-Slap and Earthquake is slightly better due to opposing Beldum's Iron Head being not very effective against other Steels. In addition, it also hits harder than Charizard's Blast Burn ever would and is more tankier.
