Have a look at some other IC threads like this and this and you can see they provide a lot more information, as well as a firm starting point/story for their players to continue from.
Try to include the rules again, and a player list. Then work on building up your introduction slightly more. I'm not expecting you to copy those, just take one or two pointers . It doesn't need much work to be approved.
It is left unapproved. If you want me to, I can PM you the text you wrote in it. However, remember Magic advised you to flesh it out a bit before resubmitting it to make the players a bit more orientated :)
