Where on the site (or on other sites) can you buy card sleeves with GoT characters on them? I found one website that sold Jon Snow and Melisandre art sleeves, so I bought a bunch of the Jon Snow ones, but I play Targaryen and would love sleeves with a dragon or some other Targaryen symbol/character. Do they even exist?

there is only Jon Snow and Melisandre. A few years ago also Cersei and Jaime was released.

note, that all of them are limited, so when gone, they are probably gone forever.

Well that's unfortunate… I can't help but wonder why they wouldn't release sleeves for every house.

Why? Because they test the waters with limited releases first, so they don't lose money…

Aren't they selling like hot cakes? I can't wait for the other famous personalities from the rest of the Great Houses, including famous neutral figures like Beric Dondarrion.

I'd love to see sleeves with either Drogon or Balerion (Drogon would probably be more likely)

I was originally thinking that FFG'd go with a picture of Dany for Targ, but on second thought, I hope they go with a dragon like you suggest.
'Cause dragons are cool…cool like the Burninator!
