Guilds

Okay so something new was brought out with the Ravnica set, Guilds, I really enjoy this it has brought something extra to the magic world. Instead of just the colors their are now these guilds that mix magic colors. It makes you want to play multicolor. I think it is really fun. If you want to find out more about the sets you could go here: Boros Legion, The Selesnya Conclave, House Dimir, The Golgari, The Gruul, The Izzet, The Orzhov, and three more guilds to come in the next set. I don't know if they will take the guilds beyond this set but it is fun anyway.
Oh and again this is just a picture I found on the net.
