Don't know if this is allowed or not...
So today I caught a shiny Sneasel and I want to train her to at least level 40 before I do more hunting. Currently, she is level 34. The moves she has are Agility, Icy Wind, Fury Swipes, and Faint Attack. I'm trying to avoid using TMs unless I must. Keep in mind that I've beaten the seventh gym, went through Mt. Coronet, but I haven't beaten Volkner yet.
What are some good trainers (Vs seeker) or wild Pokemon I can battle?
