Errrm... Nathan at the moment these are £50 a deck at the current exchange rate thats $75 a deck... or $300 a set. You really wanna buy these at that price? Or you could get a variety box, a couple gold arcanes, a hell of a lot of stuff from E, just about any deck you want, etc, etc.
Give it a few months and they will have dropped down to $15 a deck, buy them then.
