Groudon on Tyranitar raid counter guide

Not really; I believe you can use it. It's not very good but still usable with stab and if it does not have any better moves.

Earthquake is generally better against things weak to it and not Solarbeam. Solarbeam beats it in neutral scenarios like this. They may not be listed because Groudon isn't super viable to begin with, since Tyranitar already has a double weakness to a high-attack Pokemon.
