I’m loving everyone’s responses, and I’m surprised and delighted by some of the choices of Pokemon.
Back before I started only collecting Gyarados Cards, I aimed at collecting Mewtwo cards as he’s my favorite second Pokemon.
To this day I still have quite a lot of Mewtwo cards. I have a completed collection of Volcarona cards, as well as many Scyther, Scizor, Alakazam, Golduck, and Dragonair cards.
I need to post that side collection at some point. XD
I just got back a PSA 10 Reverse Holo Expedition Kadabra. It’s one of my favorite artworks of him. I’d say Alakazam is a close choice to Jolteon/Gyarados. Kadabra ties into that evolution.
Speaking of Alakazam, the Lv. X artwork is pretty sweet.
I’ve been doing this for a while with Umbreon cards. Not my favourite pokemon, but it always seems to get fantastic art on whatever card it gets. Also have a lackluster Milotic collection coming along. If I had to choose another, I’d probably go for Kyogre. First pokemon I ever got to lv 100 in the games!
