I'm locking this analysis. From what I can tell, there's a bit of a  conflict over ownership of this analysis, though that may just be  misinformation. However, there's a larger issue:
It's obvious that the user has not tested any of these sets, or at the  very least none of the lower tests, or else he would have figured out  the following obvious mistakes:
- Slowbro learns Grass Knot, making HP Grass a poor choice.
- Trick is illegal with Regenerator.
- Slowbro does not learn Hydro Pump.
- Setting "Coverage" in a moveslot is not okay.
- Psyshock is the move Slowbro gets. PsySTRIKE is the Mewtwo-exclusive 100 BP version of the move.
- The ability's name is Regenerator.
- A set should not have undefined EVs at the time of posting. At least throw something down.
ALL of these things should be solved either through common sense or a  slight combing of the Veekun or Serebii page for Slowbro, one of which  the OP even LINKED to. Furthermore, Slowbro is a high-priority Pokemon  in this generation, and with the lack of due diligence on the part of  the OP, I'm not especially convinced of his ability to carry out this  analysis competently.
Barring said assignment conflict, I'll be taking this analysis over. Until then, this analysis will be locked.
