This can tutor Divine Favor in an aggro build

Good tutor for libram of wisdom. Lots of potential here.

Thank god Prismatic Lens is 4 mana...

It's almost always going to be used for Hand of A'dal.  But look at the 3 cost spells:

Day at the Faire: it's a corrupt card, so if you could play a 1 cost right after this, you could play the corrupted version for free maybe?  Probably no one will run this still.

Equality: No one is running it at 3 mana when Barov exists.

Hold the Bridge: Weak when used on this card since it can't attack right away, but you do get a 5/2 divine shield for 3.  Comparable to Goody Two Shields I suppose.

Gift of Luminance: Really good, turns this into a 3/1 + 1/1 divine shield pair.

Righteous Defense: Not bad card, but since it's situational it's unlikely you'll want to use it immediately and early in the game.

It’s nice it can search out equality, city tax, and righteous defense. 

I don't know exactly what you play this with, but it is a sick card. Hand of A'dal would leave behind a minion that's too low health. The new Vitality Surge could make this decent in big pala I guess. I don't see any other cards worth running for this.

Sick tutor card.
