So TCG's been around for ages and especially in the last couple generations has leaned harder on the actual character part of the game. Obviously most of those favor the "major" characters (bosses, important story characters, etc) but like I mentioned in the things i like thread, even more obscure characters like Daisy have gotten a card now and you can find a few examples like her throughout the series' history.
But one character, or set of characters, that surprises me in never getting a card of any sort are the Kimono Girls
As far as these "quasi-important" characters go I think they rank up there for a few reasons:
-They have a very distinct design, and were one of the few trainer classes to get official art back in the day.
-You MUST encounter them in the story of GSC to get Surf
-They got increased story encounters & importance in HGSS
-They got TWO episodes in the anime! Plus another cameo
-A whole dedicated webisode
-Eevee trainers. Especially in the modern era, Pokemon loves leaning on Eevee so you'd think this would be a slam dunk.
But surprisingly no cards at all. The GSC-era wasn't super big on trainer cards in general, though even Mary got a card; in fact she wound up getting another in the Expedition-era and a third in the EX era. But the HGSS era? Where they became even more important? The era that gave Sages (not even the Elder, who had a unique trainer class), the Flower Shop Girl, and Copycat cards?? And its not like the modern era fully shies away from looking on the past, you'll see random trainers crop up here & there even outside of Character Rares
But really this is a backdoor to my thoughts on: it's just indecipherable what the TCG decides to and to not make into a card, even when it makes sense to. Like hey here's a fun couple of factoids:
-Silver did not get a card until Crobat V got a character rare reprint. Yep! Not even in the Japanese-only VS set
-Red & Blue also did not get cards until around Masters. Red's first card was the August 2018 "Red's Pikachu" promo (after which he got a few more cards with the Let's Go focused sets), and Blue didn't get a card.
-Despite appearing in Let's Go, which had multiple sets dedicated to it, and numerous Rocket cards over the years, Archer has never had a card. Neither has Ariana. Petrel & Proton got a card (singular, they shared it using their stock art; HGSS era) but not the 2 bigger bosses; the closest they've come to getting cards is when they were nameless Rocket Executives and were on the Rocket's Evil Deeds cards.
-Despite using normal trainer class sprites (Lanette actually had a unique overworld sprite at the time, even if her design was different in the TCG), Bebe & Cassius DID get their own cards.
-I buried the lede on Red's card; he was the first protagonist to get a proper card at all with his Promo. Until then the only time a protagonist appeared in a card was Dawn making a background cameo in a card focusing on her mother (Anime!May and Anime!Dawn had some promotional cards). Masters clearly got them to rethink the marketing power of their characters; these quite a few of them have dedicated cards and barring that will get Character Rares.
-If you were curious, the current player characters to not have a focused card (named after them or prominent in the artwork) on them are Ethan, Kris, Lyra, Hilbert, Hilda, Elio (Sun boy), Elaine (let's go girl), Chase (let's go boy), & the SV Kids (but the SV era is still young; if nothing else we'll probably get a Friends of Paldea at some point).
-Also technically Leaf? Leaf's situation is weird, the FRLG design is referred to as Leaf in merchandise and in Masters but her counterpart in Let's Go (who did get a card) is Green (Blue in Japan, obviously). And "Green" DID get a card, but "Leaf" has not.
-2 of the 4 Furisode girls got cards, well after they showed up in XY. One of them is even playable in Masters....Kimono girls in shambles over here
-So many cards based on random trainer classes or characters who aren't even really characters, but will overlook other actual characters,
If there winds up being a Johto follow up to the Pokemon 151 TCG set, I can see some of these Johto gaps being filled in, but in general the TCG's relationship with characters...a little mysterious.
