I made my own story that takes place after yugioh GX, and there are seven new shadow riders who are not only after the sacred beast cards, but are also after the egyptian god cards. The cards I am going to post here are from one of the female shadow riders named Emily (who notoriously likes to refer herself as "Princess Emmy"). I don't don't know if they are any good, so thats kind of the reason I am posting them here, to get good and bad comments and see how they can be improved, because I intend on revising my story A LOT.

Okay, so those are the cards. So please use constructive critisicsm, and please MAKE COMMENTS!!! That is why people post cards on here anyways, right?

well very creative, only the monsters are a little weak.
otherwise sounds like a good set of cards

They are weak because when they are being attacked, their effects jump in. For example, if you had Royal Princess Purple and Royal Princess Green on your field, and your opponent attacks, due to both cards effects, there would a a 1500 point difference during the damage step.

but they still get smash'd just as easily with magic and trap cards. unless you have royal princess orange out.

you need to have all of your high level monsters out simultaneously to have an effective chance of surviving.

but I do like the royal guard token idea.

Pretty unique set, i like it.

Thanks for the comments, and i changed the effect of Supreme Princess White. I figured since she is kind of hard to get out and that is her only effect, that makes her kind of lame. Also, in case nobody else figured this out, the effects of these cards work for every card with princess in their name (like Princess Pikeru, Princess of Tsurugi, etc.).
