So I had some problems catching Banette yesterday, so I had to trade for a Shuppet which I then bred. I've also updated my team's movesets and done some more grinding since my last update. As soon as Shuppet evolves and catches up with the rest of the team in level, I should be ready to take on the Elite Four!
Pidgeot / lv64 / Return, Fly, U-turn, Roost
Gothitelle / lv64 / Psychic, Energy Ball, Future Sight, Heal Block
Rotom / lv64 / Rain Dance, Thunder, Hydro Pump, Ominous Wind
Banette / lv51 / Knock Off, Protect, Will-O-Wisp, Screech
Umbreon / lv63 / Toxic, Protect, Moonlight, Dark Pulse
Noivern / lv64 / Boomburst, Dragon Pulse, Air Slash, Super Fang
Edit: Shuppet evolved and everyone's gained a few levels!
