Thats really cool, I'll share what I made for my Father. Even though he doesn't play the game he knows how and understands the concept/appreciates the game.
I'll give some background, his real job is as a reference archivist, and he almost became a monk a long time ago. He is also Quaker and thus a pacifist, so I tried to work that in.
This isn't the one I gave him, its the crappier first attempt. I almost have this down to an art though. Though I think I wil stop doing black bordered cards since it makes it 10 times harder.
Flavorwise, He found some old inscriptions while working in the monistary library and uses them to pacify everything.
Yes its printed onto a real magic card.
