Confusion or Water Gun + Water Pulse and Psyshock or Psychic

Confusion and Water Gun sport identical energy generation, though the former offers greater damage output. Either can be chosen depending on typing coverage needs. 

Water Pulse is a poor move and costs quite a bit of energy, but is an option for extra coverage if needed. Psyshock and Psychic perform very similarly and share identical typings, though it's recommended to pick one due to redundant coverage. The former costs less energy and is generally more preferable than the latter.
