This is a Platoon deck. Platoon is a game type some friends and I made up that basically combines EDH (minus the highlander bit) and Pauper - the commander is a legendary creature, but everything else must be common. Sorceries, instants and enchantments are restricted to a maximum of 2 and can only be cast if the commander is on the battlefield. It's a work in progress.

Side Note: I realize that Trinket Mage is an uncommon in Scars of Mirrodin, but he was a common in both other prints so I'm not sure on the legality of the card.
