Every Duelist likes to have some accessories on-hand when they attend a tournament, or just to have them because they look cool. Some people collect OCG cards, others desire specific playmats, and we all know about Rodrigo's pink elephant. Several people (myself included) like the look of customised card artworks, and tend to use them as Token cards for various effects.
There's a few active threads on Pojo and DuelistGroundz covering this topic so you can check out plenty more over there, but here's a few that stand out. Of course, the vast majority of these aren't tournament legal, but people often remember "the guy with the cool custom cards" when they go to an event and it's another of the little things that people like about Yu-Gi-Oh!
Oh, and check out this Dark Armed Dragon too:
