Ok I know I literally just posted but 10 minutes later this wild Jolteon popped up at a lure then I evolved and got my Flareon
@mark there's a way to make sure you get the eeveelution you want. In the original show there was a trio of trainers each with one of the evolutions. If you name the eevee you're evolving according to that, it seems to work (example, I originally named that eevee Pyro and I got the flareon). Jolteon is Sparky, and Vaporeon is Rainer
