 4 mana draw 2 is obviously inefficient. So we'll have to see if some sort of crazy game plan or combo can be enabled by the tutor effect. Definitely has potential to be good if drawing your 2 lowest cost minions enables your win condition. I can't envision what that looks like right now, but hey, definitely a possibility

So that's the "???" announcement? 

I was expecting something special tbh, kinda disappointed again 

I was hoping for an announcement on how to solve the issue for the excess of coins in mercenaries. No. It was a 4 mana draws 2.

Now compare to Crystology

 Crystology usually didn't enable OTK combos. I can't think of what OTK this will enable, or if one will emerge from the depths before this rotates, but honestly, I wouldn't be shocked if it happened.

Overall, I think the consensus is right that this is trash... unless it's broken.

Actually, crystalology was part of the draw engine that enabled the Holy Wrath - Shiv otk deck!

Doesn't demonhunter have enough draw cards? Seems like half their cards are draw.

ok this better look good in golden. if they only add barely noticable smoke/wind effects and just some glow, ima be very upset

Now compare to Crystology

Sure thing:
Different class
Different manacost
Different expansions

And most importantly:
Different applications.

As mentioned, Vanndar can be drawn this way. Might be good might be too costly. Still a tutor card draw.

Lol 4 mana draw 2 cards. Worst arcane intellect. It's the opposite of powercreep 

It's powerdecrease

Bruh i was expecting something exciting from the ,,?" xD
Like a change to certain game mode or in-game systems (dust) change
I didn't expected card.
But this card might actually be really good. Tutor card draws tends to be pretty good. And this one can draw Vandar. 

could it be good for Vanndar Stormpike ?

Maybe. But it is slow as hell. Turn 4 draw, turn 5 play a 4/4, turn 6 hope to top deck something good in order to start to play. It seems slow as hell to me. Aggro will not wait. Other decks maybe. 

I don't know why this isn't 3 mana, is there some broken combo mechanics with it that I don't see yet ?

If this was a 3 it would allowed DH to more consistently have Vanndar Stormpike on turn 4. That's what I believe

this is a combo card. draws the new legendary in a spell heavy deck, like draw the legendary and Argent Squire for OTK  turn.

overall unique and powerful

Definitely agree here, its really good and I think they balanced it off of Arcane Intellect and bumped its cost by (1) for the specific condition.

This has to be the biggest disappointment... this seems like a trash option for a class with brilliant draw...
