>>48268862nothing is inherently wrong with the idea of a SpAtk Technician mon really, but there are only two of them (Roserade + Mr. Mime), four if you count Smeargle and Toxtricity
unless I missed one lmaoThere just aren't that many half-decent special moves with a base power that's 60 or lower compared to physical moves, especially when you account for what moves they can actually learn (e.g. Twister could work, but only fucking Hitmontop gets it; Ominous Wind is good but only Scyther gets it, etc.)
the ability itself is good and a SpAtk Technician would be good on paper, but the only one that could potentially do anything with it is Smeargle (who, if you do decide to build SpAtk instead of Atk, would have almost half the options for potential moves in comparison). Most people just avoid the ability entirely for Roserade/Mr.Mime/Toxtricity.
