It's been over a decade since Duel Masters debuted. The manga spawned a trading card game, which is still widely enjoyed. If you've never played, you'll need to know something very important: bring sunglasses.
Here is what Duel Masters trading cards used to look like.
Over the years, the cards have become increasingly... busy. Which is fine!

The art is dramatic and all, but man, it sure is difficult to make out text! Maybe it's just the background of the original photos, but I keep having to hold my hand up to shield my eyes. I blame the increased use of turquoise. (Seriously! Stop with the turquoise.)
I haven't seen the full deck, so I can't say whether or not all of them are as eye-melting as these. But you got to give the Duel Masters folks credit: Dull, these cards certainly ain't!
