Wow, all the suggestions above are fantastic. They all have my +1.
Also, an Elite deck designed by T11 would be nice. With brand new design and available only to Elite members. A cool touch would be to print some every year and somewhere on the back of the box to have the names of the Elite members of that year printed.
So when got Elite status, at the end of the year you would get a rare deck with your name on the back of the box. I'm already excited.
Plus it could have a cool name like "Elite Deck" or "Theory's Elite" or well, the cool names you come up with.
