WHMT MTG Community Set

Let's make a Magic the Gathering community set! Never played? Unfamiliar? Not an issue! It's really very simple.

My thoughts:

-Size ~ 60 cards, should be fairly diverse in terms of color, type, and the ratios common/uncommon/rare/mystic rare ratio should be realistic.
-Theme - card mechanics (custom and standard) should reflect this
-Art - determined mainly by theme
-"Flavor" should adhere to the color pie (exceptions should be made very sparingly- don't butcher it):

Spoiler:

Program DL for Windows & Linux (unnecessary, but gives cards visual appeal): http://magicseteditor.sourceforge.net/download

Here are some examples of cards utilizing custom mechanics, although they don't correspond to any theme, yet:

Spoiler:

I will also help with syntax - ideas should be worded correctly.

Not a huge Magic player as you know, but this will be fun. Post-apocalyptic theme maybe?

FO3!!!! (or ofcourse Metro 2033)
