Omastar big time! One in fossil would have been great. Also a 1st edition Mew. There’s a decent amount of mews but no wotc 1st edition. Besides that there is tons of Pokemon that get skipped over whether it’s 1st edition holo’s. Full arts. Rainbow Rares. Ex’s etc
There is only one. Every other pre-generation 4 pokémon mentioned have had their choices actually justified. Omastar and Exeggutor back in the day had more unique slots then what Holo and even Shnining/Crystal was, a card made by OOyama (and be biliungual) and Masaki (a little fuck you to Kabutops).
