Recommend one card. I will fill a binder with the recommendations and show it off as I go along. Keep it to English or Japanese and reasonably priced. I have other goals but I want a cool binder to work on.
051/DP-P
First card that came to mind: 27/236 Litwick Japanese Gym promo. Just a cute Litwick artwork I recently bought for my binder
EX Ruby/Sapphire Wailmer. Great art. If you want to bling it up get the reverse holo version.
Japanese Southern Island Wartortle
Mario Pikachu (XY-P Promo 294)
023/095 Japanese holo Blastoise from team up (tag bolt is Japanese name). One of the best Blastoise artworks imo.
Growlithe from Vending or Quick starter gift box. Great idea btw!
Primal Kyogre EX 149/160! My favorite modern card!
Japanese Dark Gyarados Holo, or Trophy Pikachu #1 1997
E series 2 Aquapolis Cubone!
Cyndaquil xy-p. Probably the cutest cyndaquil card and my personal favorite
Dragonite game boy promo
Rayquaza ex Gift Box 018
I know you said one card, but these two just go so well together in a binder.
Can’t get enough of this card
Mt. Fuji Surfing Pikachu
Ooyama’s Pokemon Machine
1997 Toyota Pikachu. Rare low pop vintage but fairly affordable still. Also the arcanine is indistinguishable from the CD promo so the pikachu is the only true toyota promo left booklet or not.
Pichu from the Totodile Side Deck.
Shit I never knew that! So how does PSA decide what to put on the label between CD promo and Toyota? Whatever you tell them?
