The Aurum.
Oh, man, The Aurum deck.
In my opinion, one of the most beautiful decks out there. The laser cut box, the thin borders, the extremely intricate designs that didn't overwhelm the awesome customization, and the sexy, sexy handling. Everything about this deck just seemed so cohesive and refined.
The luxury crowns are ridiculously awesome too, with the sweet box, classy back, and neat court cards, I'm also told they handle pretty nice. but I think the Aurum comes out on top for this one.
