So out of all "muh patterns," the only 3 to stand the test of time and be in every gen are the classic start trios, 2-stage Normal-type mammals, and pseudo-legendaries.

Regional birds and Pikaclones come close but have some ambiguities (some birds are 3-stage while others are 2-stage; does Fearow count; Pelipper originally had the same BST as Swellow so does it count; Wingull is available before Tailow and more widespread so is it the true regional bird; does Pichu count as a Pikaclone if it's directly related to Pikachu [if so does Alolan Raichu count]; some consider Marill and Mimikyu Pikaclones; and so on).

With GF ignoring some of the arbitrary unspoken patternfag shit (no lesser legendary group in Gen 6, no more Mew stat clones, evolving legendaries, mid-gen Pokemon, Necrozma isn't Dragon-type, etc.), which of these 3 do you expect to be broken first? After shit like Silvally and Cosmoem, I expect Gen 8 to lack a "true" pseudolegend but have something really close like a 3-stage 598 BST Pokemon that can't breed but is never officially called Legendary so it'll drive the bulbapedo spergs insane.
