but you're saying a jigglypuff from billions of years ago and put through a jurassic park filter is legitimate? of course you won't see anything wrong with the fossil pokemon design philosophy from gen 1-8 suddenly being thrown out in gen 9 when you have a time machine that can bring armaldos and omastars to the present. but it doesn't do that.
