The gold shiny Electrode is my favourite from what I’ve glanced over so far. Overall the fantasy theme/styling is pretty interesting.
Edit - Looking at the cards on a bigger screen, the non-Rainbow Celebi FA is really nice! And the はくばバドレックス SR (Sorry no idea what this Pokemon is called lol) is epic!
Definitely some cool if a bit OTT cards in this set.
Japanese Pull Rates are pretty darned sucky, but again then I still see that Orbeetle FA from Volt Tackle in my nightmares so I have some negative some bias. It really makes sense to just buy the singles and open one box or so for fun.
Saya Tsuruta’s male Indeedee was one of my favorite cards from recent sets, so I’m glad to see her doing a full art, but it took me a while to realize that Blissey is sitting on a chair and not just melting.
As for the Calyrex confusion: Calyrex can ride either Glastrier, which makes it Ice Rider Calyrex or Spectrier, which makes it Shadow Rider Calyrex. The horses are separate Pokémon, so we can expect to see them in future sets.
What surprises me though is that we still don’t get to see the new Regis. The next set might be a set with all Regis or one set for Regieleki/Regidrago each.
