Strictly less fun Capricious Efreet. I kid, I kid...

So in a multiplayer game do you get to choose which opponent? It seems like it can become really hard and bothersome to determine a singular permanent of theirs at random when you have three+ opponents.

EDIT: I guess the # of opponents doesn't matter since you can just first roll a die to determine the opponent. Still, if that opponent has 23 or so permanents it can be pretty hard to determine the random "target".

Rolling a die to choose an opponent first skews the probability of hitting a player's permanent if e. g. one of them is controlling twenty tokens.

So either build the choosing of an opponent in the rules text or solve the deign issue in a fair way.

I personally think this would make a splendid Curse as well.

Ya, upon further thought, I'm scrapping this design. It just isn't going to be fun to play with. If I bring it back, it will be as a curse for the reasons you guys provided, but for now, I'm going to pretend like it isn't in my design file until I come up with a replacement.
