I think the deck in the photo is an ordinary Midnight Edition. The red-stoned ring is "foreshadowing"...
And yes, the Special Edition in this case isn't some insane money-grab, but is actually being offered at nearly the same cost as the regular. Neither deck is all that expensive, and the April Fool's Deck is even cheaper than that. Thus, I want them all!
One guess on the AFD: remember that picture of "The Handlordz Wars" he was selling on the site? That on the back of a deck! Detail would suffer, but I think it would still look cool, even if they only reproduced a section of the original image.
