Hi i was wondering if you could use penny sleeves to sleeve the cards if that is possible. i just want to protect the cards from damage. i sleeve all my games if possible. if you could let me know.
Yes -- I use penny sleeves. I used them first to slide in errata sheets for my first edtion cards (minor updates, language consistency, artwork for environments), and then the rest of the expansions got penny sleeved because they were feeling jealous.
I use UltraPro Sleeves - 2 5/8 x 3 5/8", and they seem to fit just fine.
Welcome to the forums Ruby! If you look up at the top of this forum youll see a 'New to the Sentinels Forum?' stickied post, and in there is a link to a thread about sleeving your cards. Check it out and have fun!
Thank you for helping me out.
Where's a "report spam" button when you need one..
Scrubbed. 
There was none? Did the cards have more flavor text or something?
I don't sleeve my pennies. They seem pretty durable. Besides, they just sit in a jar anyway.
