Shot in the dark, but I’m hoping to be wrong. I evolved a purified Porygon-Z earlier this month. I do not have a second move on this mon - so it learned Tri Attack. Is there any way to get Return on it as well at this point?
No. The ETM won’t teach it return and in addition the community day moves always takes the first spot as does return. I think the only way to have return+CD move would be to evolve with return on it, and then ETM into tri attack after buying the second move.
Unfortunate, but makes sense. OK, thanks for the information!
