Okay well for starters, I think we can agree on having all the characters.... The main eight, Hiyoko, Miru+Kaku (probably as a single card?), Albert, Azami, Rabu, Mr. Urushihara, Mr. One, Rainbowbeaks, all the various incarnations of Shuu and the Kazuakis (which now needs to be the name of a band), the King, Ryouta's dad..... anybody else? Headmaster bird? Prime Minister Shoebill?
