Magic Set Editor (MSE) is a free program for designing cards for Magic the Gathering and other card games. MSE can output images, print cards, show graphs of a card set, and generate 'spoilers' of a set for publishing on the internet.Magic Set Editor is widely considered one of the best editors available. It is no longer updated but works on all versions of Windows. It is simple to use and intuitive where other similar programs overly-complicate the process.
