[H]Bastion, Mark of Ninja + Origin Bundle + Natural s. 2, Magika + gmod + ss3 bfe [W] Offert

Hello, first of all sorry about my English.

I just discover this site so I'll trade my key that I get twice from some humble bundle.

I have Bastion, Mark of the Ninja steam key.

Edit : Just got Natural selection 2, Magika and 2 dlc, Serious sam 3 BFE, Garry mod and city in motion 2

I have also Origin key but I don't know if I can offer them on this site. If no please apologizes me.

Here is the Origin key I own :

Dead space
Burnout Paradise: The Ultimate
Crysis 2 Maximum Edition

Thanks you !

Edit : I am not really interested in steam card sorry.

Edit : Game I would really like : starbound, any fear, any bioshock, fallour 3 and nv, far cry 3, skyrim dlc, oblivion, FF.
For any of these game I can give you any game that value the double of you offer. Example : Starbound 15$ I can give you mark of the ninja 15$ + natural selection 2 20$. I don't care about whats I give if you offer one of these game.
