6,000 source Crystals for Vixen and Jay each. You have to buy her by going into Cheetah's shader/skin sets and you get her primary and alternate colors. You can get enough source Crystals for both if you manage them properly without putting anymore "real money" into it. Story mode gives a good amount.What do I need to get Vixen and Jay Garrick? I bought the Ultimate Pack and they weren't included.
