Any tournament-legal version or printing of a card in a Standard-legal set is okay to use when playing Standard
The Hoppip line also has the same artist in Neo Genesis, Aquapolis, EX Team Rocket Returns, and HGSS (off the top of my head)
You can either call this a natural result for a beautiful card thats over three years old at this point, or you can blame the new Mega Darkrai card for bringing the communitys attention back to AKIRA EGAWAs artwork
Its one of the most understated cards in the entire set, especially compared to some of the other Alternative Art Scarlet and Violet cards, but thats what makes it so desirable
Also the free haste makes triggered combat abilities like Balefire Dragon's more powerful since you get to use them immediately
Mostly, collectors and investors should be on the look out for about 25 Pokmon first edition cards that are the most valuable, according to Old Sports Cards
