I keep going back and forth on whether i think its too weak or too strong, so i guess its about right :p
On the one hand, comparing it to precognition, you might consider raising its cost slightly. This card has the advantage (well i think its an advantage) of forcing your draw to be a pillar.
On the other hand, its more limited than precog, since you have to have emerald pillars in your deck. And of course you don't get precognition's view of your opponent's hand.
Draw power tends to be the domain of

, so there may be some resistance to the card on that front.
