64 of the 113 Pokemon are Gen 5 mon, so that means over half of all mon not in Gen 7 sets are Gen 5. This is why we need a dedicated Gen 5 set or at least have the remaining sets this gen with 10+ Gen 5 Pokémon in them each.Look I'm super sympathetic to the fact that certain Pokemon fall through the cracks for too long (Sunkern and Sunflora not appearing in the Johto-based set last year was bleak), and that the TCG is pretty much desperate with its Charizard pandering to sell packs in Gen 7, but there are still SEVERAL sets left before Gen 8 for a lot of these forgotten Pokemon to appear -- GG End's still got a good 20-30 cards to reveal, and there's also Sky Legends in April (54 cards), and Miracle Twin (95 cards) after that, BEFORE this Remix Bout set comes out in July.
I keep a running spreadsheet of each Pokemon's last appearances, and 696/809 have appeared in the SM era, which isn't that bad considering the 113 omitted include a dozen-plus non-Togepi/Riolu Baby Pokemon (which, until Double Blaze, were all but abandoned for a decade) and Kadabra. Especially when doubling up on popular Pokemon has been an aspect of the Pokemon selection in the TCG since jump. Kadabra aside, the last time a Generation actually featured every single Pokemon in the TCG was Gen 4 a decade ago. I don't expect all 112 remaining Pokemon to appear before Sword and Shield but it could be worse in terms of featuring everyone. *side eyes Gen 5's TCG era*
GG End could have the Axew line, because it's Dragon related.
Sky Legends seems to be based on Flying Pokémon, so that could mean we see Tornadus and Thundurus due to them being Flying Type Legendaries. I'd also like to see Pidove, Ducklett and Ruflett lines make it to this set.
Remix Bout may be a Starter related set, which means we could see the Gen 5 Starters finally appearing in this Gen.
Miracle Twin may also feature Pokémon in doubles, so like Throh and Sawk, the former of which we haven't seen yet.
I'm guessing we also have the mini set after Remix Bout and the final set in September, though that one's probably only going to have reprints.
