Collectable Stat Cards: Set 10, Leadfoot is out. It is the ninth set being released through the Collectable Stat Cards feature. 1 card cost 15 RP, 3 cards would cost 42 RP. Zynga might throw in a 20% Off on the cards every now and then, so stay tuned!
amount of Reward Points you are going to spend is not worth the loot
and skill points you get back in return. I would not spend my Reward
Points on this feature personally.
