As far as sets, I hope to see an Evolutions 2 featuring the Johto generation
And concerning choices, I’d really like to see holo-rares come in a variety of foil patterns rather than the uniform vertical stripes we currently have.
Gold Star Deoxys
Amazing Rare Ho-oh
Inverted color rarity
Bring back Dark/Light Pokemon
Bring back Character rares
New form of Chansey next gen like Galarian/Alolan
Southern Islands Special Set using Pokemon in the Background that arent used till now
A dark-theme criminal Set with evil as Keyelement
A Set with Charizard on the Common Slot and Caterpie as Secret Rare
More Combination of existing Art + Pokemon
Special arts featuring shiny Pokemon. Shiny sets are incredibly successful, and special arts have singlehandedly made SWSH TCG the most exciting era since the introduction of full arts to begin with. Hidden/Shining Fates were cool but the copy-paste and MS Paint Bucket style of shinies leaves a lot to be desired. Merging the two would lead to the best Pokemon set of all time, full stop.
I’m very excited for Celebrations. Reviving things like Delta Species and Gold Stars was #1 on my wish list for a long time. Excited to see the pivot towards collectors from Pokemon and we can only hope it continues!
For me, the best part of the amazing rare is the subtle gold trim on certain features. It’s barely noticeable, but it adds that extra level of class and sparkle.
Personally, I’d like to see an amazing rare Porygon. It’s kinda a gag since it probably won’t be playable, but the rainbow effect could go really well with a digital-looking background, and it’s a tribute to one of the original, though mostly useless, trophy mon. But, hey! Why not dream?!
Amazing Rare Deoxys to go with the Amazing Rare Rayquaza would be nice. And they could do some kind of aurora effect in the background.
An entire set of new Pokemon with the original WOTC card template. They’re teasing it with Light Toxtricity for Celebrations. Let’s just get a whole set of it.
