Looks like they have a VIP program that allows you to get free Pro Packs with membership. Not sure about other perks. A lot of players are actually the same, but they have this Spring Festival promo which gave the Master Lin with buzzer beater instead. Not sure if there are others, maybe their trade deadline promo which is still going on has a few. Also, they are very behind on TOTW which also has a different name.
