Depending on your team structure, either Jolteon, Vaporeon or Sylveon. Don't worry about leaving early Darryl, I've done that a lot too.
What's your strategy for team building? Your Fire team was strong, but it looks like the teams you used today had less success.
Unless there's a theme, such as weather based, it's just a matter of filling in particular roles. At least one special bruiser and physical bruiser, a booster, a tank, a scout, and something else that could be a lot of things, like a mega or a para-flinch kiss. Also, hitting stone edge when I meant to hit Earthquake on your T-tar. :c
