Hi there. I have several thousand Magic the gathering cards, possibly over 10k at this point, that I don't really need. I was thinking about giving my room a nice blue tone by covering the walls with them, but I don't think I have quite enough blue cards for that. So at this point I'm kind of just wondering what I COULD do with them. A nice thing about them is that I have 30-40 of many of the same cards, so if I want a large patch of the same color for some reason, it's possible.

For those that don't know, Magic cards are the size of a normal playing card, but about twice as thick and have detailed fantasy art on them. Primary colors used are blue, green, red, black, and white.
