I admire you artwork skills and i think this a beautiful design, but idk if theory 11 will take it though. I am not saying your design is not good, it is elegant but idk if it is marketable in a sense. Sadly many ideas are good magically and visually, but not economically. I think some decks have been very successful because of the theme they had. First there were bicycles, the basic bar none. Then there were the color variations and expansions liek the Ghost Deck and Black Tiger. Then, especially on t11, there came new deck ideas. There was the new expanded take on the angels on the cards which became the Guardians. There are decks from the prestigious casinos, Wynns and others. The Centurions came in, the deck of the warrior, nobody had done that. Smoke+Mirrors and Split Spades were made, homages to great magicians, unique designs. Then Propaganda was unveiled, the military grade deck. These are all attractive designs, but hold a new significance in themselves. I reiterate that i am not down playing your design at all, but i am simply saying that, in my humble opinion, a new design is needed, something that no one has ever done before.
But that's just my tw....three cents.
