so these are all series B, are they limited/sold out? I have 2 decks of series A blue, should I open them up or keep them sealed once I get this set?
The Black Label White Lions are still on his site at retail. The Series B Blue are available as a boxed set with an autographed deck for $24.95.
But you would know this if you LOOKED AT THE WEBSITE.
As far as opening or not opening, well, that's entirely up to you. The two series are similar, but certainly not identical to each other. Performance-wise, both are equal. Appearance-wise, they have different elements - jokers and Ace of Spades in particular. They're both subtly marked, but the system is a little more refined in Series B than in Series A.
