I was on the Asmodee store site noodling around and found that there are official card sleeves for all of the core box heroes and Cap up for pre-order. There are also sleeves with the different card back colors if you prefer that. Each has 50 sleeves, plus a clear sleeve for the hero/villain.

Yup saw that. Thanks for the post. The Orange Marvel sleeves I pre-ordered a few boxes and it is an easy remedy for integrating print and play like Ronan. I really hope FFG release more print and play I would love it personally. Looking forward to the sleeves because it would add more spice to my decks instead of solid color sleeves.

Yeah, I'm going to buy a bunch of the orange-back sleeves and then a set of the hero sleeves for what they release. I don't mind resleeving as much as some people do, so it's not a problem for me to have each hero with their own sleeves. I need to get a nice print-out of the Ronan set.
