Not sure it's worth effectively having 1 card less in hand to gradually and unreliably find out what your opponent is holding but it's a fun effect. It's a cool card but it's not a competitive one.
That said I'm sure the Hearthpwn community's reaction will be to complain it's super OP and the usual "wah priest is getting all the good cards" that's plagued every single priest release so far but then why would they stop and think for 30 seconds when they could leap to doomsaying nonsense instead.

Great take on the Secret Aggro mage deck archetype! I subbed out 2 Polymorph for 2 Unstable Ghoul because I was getting rekt by Unleash the Hounds.
