These cards came out earlier this month and my local comic shop just got them in. I would love to collect them, but they are kinda pricey. $6 per pack! And they are a hobby exclusive. Which means they won't be available at Target or Walmart. Plus there are 350 base cards as well as a ton of insert cards. Ugh! I did buy three packs though and was lucky enough to pull a sketch card. I'll probably just buy a pack or two every time I go to my comic shop until he runs out.
Here's my sketch card. Lando Calrissian by Robert Teranishi.
