I actually have those 3 on GOG.com, but if you wanted to trade any 2 of those for it I could do that and just trade them later on.
EDIT: Just checked my GOG account and I don't have Far Cry, so if your trading cards are for trade I could trade it for Far Cry + 4 Magicka Cards.
Depends on which cards they are, let me know what games they are from and I'll let you know.
You can choose then the cards you like: 3x Magicka, 3x Faerie, 2x SS3, 2x Trine 2 (all different) or Maybe a Trine 2 Booster? If you also accept double cards, i can give you more ;)
Sorry, got an offer of more cards below, but if it doesn't happen I'll get back with you.
1tf key and 1 ref? gifts are going for 2 keys so 1 tf2 key and 1 ref is a good price for a steam key.
No thanks, I usually don't deal with ref since it's not marketable and I don't actually play TF2, but thank you for your offer.
