What about other Pokemon obtained from the glitch? Or just a normal colored Mew?yes this mew is illegal. because the pokemon itself is obtained via a glitch, specifically. 8F manipulation glitches themselves are legal on a legitimately obtained pokemon, however.
(it bums me out too bc those Mew have 5 guaranteed 31 IV's when transferred to Sumo, so its relatively easy to get a flawless shiny Mew)
i can hook you up with a copy of a venusaur in gen 6 or 7. write on my wall if you need it.
