Sorry I didn't post earlier. I actually was thinking of essentially the same thing in a creature form a few days ago, but couldn't think of how to deal with fractal issues... Permanent makes those kind of moot though.
I love the idea and think it will bring a fun mechanic to the game. The only issue right now is that we don't have many ways to get the opponent to discard to begin with... but I guess its gotta start somewhere
Anyhow, nice job. And Kudos to Zblader on the nifty artwork. I'll be watching crucible so I can give it some support.
As an aside,
Darkness is an interesting choice for this. I would have thought to use aether myself (due to the mind / card theme connection) but this plays off of the theft theme for dark so it works well there too.
