I use mayday game sleeves for mine because they are cheaper. I also use swan sleeves for the character cards. Here is the link http://www.swanpanasiasleeves.com/products/swan-card-sleeves-103x128-100-pack-thin-sleeves-talisman-character-cards

they fit perfectly over them. Plus you will have plenty for future expansions that will be released.

I cannot recommend Mayday sleeves, they are much cheaper but they are also much flimsier. You're much better off buying decent sleeves in my opinion.

Boardgamegeek has a nice listing anf tips on how to get sleeves for the hero cards. They even have totals of how many you will need.

And thank you all for the feedback. Yeah I just want the cards protected from finger prints and the potential clumsy spill of soda, etc.
