Hey guys, I'm trying to figure out a team to breed, and I was just wondering if you guys could give me your advice or opinions. I'm quite adament on Umbreon being the core of this team, so apart from Umbreon feel free to change anything that you deem to be better
I don't have access to tutor moves such as Foul play or Heal bell unfortunately
