I am playing with the idea of using Recycle. Here is the idea:
Mr.Mime / Chesto Berry
Barrier
Toxic
Recycle
Rest
Basically it uses Barrier first (because of the horrible low Defense), then Toxic and then Rest - Recycle - Rest - Recycle until the opponent is down.
The combo Rest - Recycle heals it always completely. I am not sure if Mr.Mime can survive it. It's Speed is not great and Defense is horrible.
Maybe Porygon would be a better candidate for such an idea? But Porygon learns Recover naturally, can heal completely using it in two turns, and that makes the Rest-Recycle combo useless.
Any comments, thoughts, ideas welcome.
