I don't think I would put possession on my 5 baned card list. There are worse cards I don't enjoy playing with.
Rebuild would probably be on it: most of the time a boring game.
Wall and Torturer: the former because I hate it. The later because it often is frustrating to all but one of the players.
And probably Scrying Pool: I don't really get it and it is annoying if a Moat is in play.
I'll leave the last one open for future use. With a small tendancy toward Gladiator.
