You referring to the Pokemon’s Attack Defence and Stamina stats?
Is this similar to the Tyrouge thing where dependent on those stats determined if you got Hitmontop, Hitmonchan or Hitmonlee when evolved?
Ok, I just caught a Female 181 CP, 87% IV Wurmple in my office.
For Mystic it appraised:
Best Attack (15), equal to Defence (15)
Exceed my calculations
This evolved into Cascoon then to Dustox
