My favorite deck I own is my Jasmine Boreal of the Seven all old border deck. Lots of vanilla creatures and an enchantress subtheme for card draw. Its fun to work within the limits of old border only, and its a great excuse to look at tons of old cards.

Some favorites in the deck are Inheritance, Festival, and Moss Monster

Do you have any gimmick/special rules/unique ways of building a certain commander?
