Before I say anything, this question is directed for the Let’s Go games.
So, I recently caught an eevee and am wondering which evolution to evolve it into, and if anyone is happy to hand me a moveset aswell I’d appreciate it.
First, this depends. If you want a fast Pokemon, I'd recommend Jolteon, perhaps with an attack or speed boosting nature. If you want a more bulky Pokemon, I'd recommend Vaporeon, with a defense or special defense boosting nature. And Flareon... Well, I don't particularly recommend Flareon unless you really like fire types.
Here, I left the stats here as reference. Hope this helps. Best of luck, ATE.
