It's not really "free" as you say. You're getting it as a result of spending like $300 at Ellusionist. I shop there too, but in order for your order to be around that amount, you gotta be crazy (unless you're getting any expensive gimmicks...but still!).
Anyways, I used to want a 1st Edition Black Ghost Deck for a while a while back, but now I don't really care. If I go out and perform for others with it, am I going to give them a whole speech as to why they're so unique? Eh. The Gold Arcanes look great, and they are what people are wanting nowadays. Get those if you seriously are going to spend like $300.
I suggest you wait till Christmas, however. I'm sure there will be additional "free" stuff along with the Gold Arcane/1st Edition BG Deck.
Anyways, I think that I would be stressed out if I had one of those decks. I would feel so guilty opening one of them up and using them, and I would feel like it would be necessary to check on the deck every so often if I do not open it. And, I would feel extremely guilty if I lost a card from the deck, or the box got damaged, or the cards wore out (inevitable).
If you're happy with it, then I'm happy with it.
