I like the anime bondage idea.
What I want in a deck is art that is clear, not fuzzy or muddied. I also prefer scenic minors, as opposed to pips or semi-illustrated minors. Small borders, unobtrusive text, and a reversible back. Some sort of depiction of the suit's element on it's cards is good too, that way I can see right away of it's a Wands=Fire or Swords=Fire deck.
Good luck to you! I hope it works!
