Its going to be cool to see how Deck Values evolve in this game.

At an extreme level, the first world champions deck may actually be worth something.

It will absolutely be worth something. Just from the fact that the world champion won with it, regardless of how good it is.

It isn't just the decklist they played. It is the literal cards they used. You can use the card they won the climactic match with.

Or other prestigious decks that are passed down from one player to another.

I think many decks will be available for cheap in places like eBay after a litlle while. People tired of playing the same stuff over and over will likely sell it and buy new ones if they still wnat to go on with the game

The question is, is this a game that will see "traditional" tournament formats? I can see sealed/blind tournaments. I can see other formats, but how many people will be willing to play a tournament where so much depends on either being insanely lucky, or (more likely), by outbidding the opposition for the über-deck?
