I clicked a link on the tramps facebook page tonight, that brought me to a wizards of the coast page that listed the following sets as playable at a tournement:

•Scars of Mirrodin
•Mirrodin Besieged
•New Phyrexia
•Magic 2012
•Innistrad

Now, here's my question, alot of my cards are older, so if I were going to show up at a friday night magic, is there a quick way I can check which cards in my deck are playable, and which ones I should switch out?
