>>57574761I think monotype final stages are fine and since Fire/Ghost is becoming a bit too numerous in recent gens and Fire/Psychic doesn't really work all that well for the type of mysticism Ninetails goes for, I think Fire/Fairy would work best if you absolutely had to give it a secondary type, plus it's an unique and pretty good typing.
>>57574879Dragon/Bug is a fucking atrocious typing offensively and Flygon isn't bulky enough to make use of it's positive defensive attributes, Flygon is too draconic in design to go with Bug/Ground as well, like many other anons in the thread have said, Yanmega feels like it should have been a Bug/Dragon Pokemon, but wasn't. I'll add another example to this that really pisses me off and it's Slither Wing, I love this big lug and it really confuses me as to why the fuck it's Bug/Fighting, I vaguely understand Great Tusk since it's combative in nature and very brutish, but Slither Wing? Literally nothing about it says Fighting, quite literally nothing and it has reptilian, specifically archosaurian features like a dinosaur that could also pass for draconic features, but it's not Bug/Dragon, it simply isn't and it annoys me to no end, Dragon Dance would perfectly compliment it as a move too but it doesn't get it.
>>57574968We don't have a singular Ghost/Psychic non-legendary and making it Ghost/Fairy would kinda ruins the whole point of Flutter Mane, I don't think it would improve Mismagius however with how shit Psychic/Ghost is as a type combination, not to mention Psychic types as a whole have become incredibly unfavorable in recent gens because of how stupid Dark and Ghost spam has become, there's Expanding Force spam, but that's the only fame Psychic types can muster these days outside of niches like Farigiraf blocking priority and providing support.
