Ye gods, man! That D&D concept deck looks like Godzilla ate Disneyland, got an upset stomach and puked in Technicolor all over the cardstock! It's, er, "interesting", to be sure, but the deck would be insanely distracting to see in action. Cardists might enjoy the attention (assuming they didn't go blind practicing with them) but I'd have a tough time using those for magic - the spectators' focus would be completely on the cards and not on the performance. It hurts just thinking of looking at them!
