For my cards, Ash always seems to choose the game I'm currently playing and bases the card's design around that. This is the very first card Ash made for me; for my 18th birthday I got a Playstation 2 (yeah, only seven years too late to the party there) and one of my favourite games: We Love Katamari.
So as you can see, my birthday Katamari comes complete with a ton of rolled-up presents, a party hat, ribbons and a cake. :D
