From my understanding, this deck, as well as the Golden Bee, were produced by the USPC China Agent, which is part of the Jarden Group (apparently a sister company as per their website and a certificate by USPC, in Chinese), so I think that would still make this an 'in-house' deck. Don't know why it doesn't have the guarantee joker, maybe because it is for the China market and they don't honor the guarantees here?
P.S. This deck is a limited deck, though I am not sure how many in total were produced (I asked the China Agent but got no answer), I was told another shipment is due next month...only 90 have been released in China to date
