That really depends on the situation... it's quite conceivable that I'm willing to settle for a mediocre over a good turn to give you a terrible one. In my first game against Tao Chen yesterday I didnt play Possession at least once because I expected him to have a bad hand, and I remember a game against Stef from a while ago where he thought for like a minute about not Minioning for cards after Goko, kind as it is, revealed to him that I did not reveal my Moat.
