Magic the Roll Playing Game (Abe Sargent)

A while back, Abe Sargent introduced the concept of playing Magic as a RPG, and I really liked it from the start. The original version had some issues, but those have since been hammered out. The general concept is to create a planeswalker character with attribute stats which define things like deck size, spell access, card repetition, and starting life. You can also add abilities to your planeswalker to allow it to specialize in certain aspects of the game.

Since then, I've been working on a Master Rules Document so there would be one unified source for my local play group.

The original articles on which it is based can be found here.
