Have Archmage Antonidas and a bunch of spells in your hand...play this. You now have 2 Archmage Antonidas in your hand where one can be used as removal bait. Seems decent cause you can in effect choose what will be your lowest minion in your hand by playing cards you don't want a copy of.
I'd probably pick this in arena if there was no better selection of 3 epics. Not sure about constructed though...
Don't really know how to judge this card. Clearly a tutor for Sorcerer's Apprentice, but at that point you have to get rid of Mana Wyrm and the chick that draw a secret to be 100% sure you'll get the sorcerer.
You're typically going to play those cards early, though, so it's not much of a problem.
