Mask Rank Ribbon

[Mewmoonmew]

This is just a general question, since I know ribbon masters are somewhat common in the Pokémon community. I noticed that pokemon that could recently get it, like Mew in SV, or pokemon in SV like Drilburr, can get the legal check in SWSH no problem. But for mons locked in, like Victini, they aren't legal (except for the SWSH event ones). Also mons like Zarude and the shiny galar birds, can't have their moves, like jungle healing. So they aren't legal technically, even if you get them from the mystery gift data bank itself. 

So I was wondering if it was an oversight for those event pokemon, as well as those that might want to edit the ribbon onto pokemon like Meltan, since it's been nearly half a decade for some of them. If Champions don't include the ribbon and hold events for mythicals. I know some people don't like that they missed out on them, and if they can somehow get the ribbon before being locked to gen 10 and up, some will likely take it

Outdated version of PKHeX aside, the ribbon is available for a species only if the species could have been used in ranked battles. If the species couldn't be obtained yet or hasn't been legitimately transferred to a game that allowed for use, then it can't have the ribbon.
