Make sure the moveset is shadow claw, hydro cannon, and then either ice beam or crunch! Hydro cannon is a move you need to use an elite tm for if you don't have it already
You don’t have the correct fast move. So every Pokémon’s fast move is what generates energy to build up to your charge moves. Ferg has Bite, Ice Fang, Shadow Claw, Waterfall, and Watergun. You want Shadow Claw on him and my guess is you either have Bite or Ice Fang
I just started the game maybe a month ago. Really into the GBL and your content! I managed to pick up a shadow toto that'll turn into a 98% shadow ferg and a 99% annihilape. I don't have access to anything XL or anything especially exclusive. Thoughts to round out the team?
