In the first place we don't know if Mustard will appear in his casual clothes or his fighting outfit. He's probably not popular enough to have an alt. It would be kind of weird for him to appear in his fighting outfit all the time when he's not always in that mode.
It'll probably be a while until DeNa starts going to release obscure characters regularly. I think people are underestimating the lifespan of gacha apps, especially if they're behind a franchise with some of the best marketing I've ever seen that it puts other American franchises to shame. Not even shilling, though you all seen it happening with all the other Pokemon games and merchandise. Because you'd think Pokemon Masters EX will EoS, but I think it could continue even beyond 10 years. But it'd be so fucking washed up like....like fucking neopets, man. There'd probably be a store by then, and the pairs themselves are augmented in a way that they can work like NFTs.
Like, if they really thought this through, they'll probably release an alt of Mustard on DeNa's 5th or 7th year. You'd probably see a lot of "what the fuck are these guys doing here" pairs by then. If you're gonna run a pachinko app under the Pokemon brand name, you're gonna do what it takes to shit out units, no matter how bullshit of an idea it may be. Look at goddamn Smash Bros., you don't think they'd be up to the same tricks with Masters? I wouldn't be surprised if all of a sudden we're getting seven Ashes, and Lillie with a hat.

A combination of being both athletic and cheerful.
In any normal gacha we'd have gotten the 2 popular character as SSR and 2 unpopular obscure characters as SR monthly unlike this fucking awful mess of everything's limited everything galar and unova mess we've got here.
None besides the newly added Korrina, which I doubt would be added to that pool Then again, we only have SS Blue for Water Pokefair and Lysandre for Flying Pokefair, so that banner's pretty barebones overall
