>>52084500 I can at least get the no final evos in some cases. Magnezone I can see having not developed prior to technology (even if one can be seen flying around in Hisui), or at least not prior to Magnemite/Magnetron moving from a ground type to Steel type.
I was going to make an argument that Wigglytuff didn't develop until whatever meteor that brought Clefairy crashed into the planet, but then I remembered that Moon Stones are still going to be available in modern day so that probably doesn't hold.
