It may not be one of the prettiest cards, but this Starmie Nice Card from 2004 is certainly one of the most fun to collect.
In 2003 a game for the Gamecube was released called Pokémon Channel. In this game you could do different things, one of them was collecting so called Nice Cards:
Nice Cards were the main collectable in Pokemon Channel. True to their name, they were nice cards that you could either obtain by answering trivia questions from Pokemon you found wandering around or buying booster packs from the Shop N’ Squirtle TV channel. Source
Those in-game cards were released as physical cards too! Isn’t that totally awesome? 
Nice Cards have a unique charm that few other cards possess. There’s something special about their green color, thick plastic “cardstock”, and unconventional format. The blurry CGI images give them a distinct aesthetic, complemented by the bold yet oddly appealing font on the back—partially written in white and pink. These cards feel like a mix of design elements that weren’t meant to be combined, yet somehow, they come together in an oddly satisfying way.
