Wow that was a long title. But thanks to Warheart we can now use the Magic Set Editor to make cards for Tannhauser. You can get MSE Here, and you can get the necessary files for Tannhauser equipment cards Here.
Update: to make sure the card titles will go onto a second line if necessary you need to copy this FILE to the data/tannhauser.mse-game file of the Magic Set folder.
Custom characters and equipment just got a little easier.
