Nice! Instead of passing on turn 2, you can search your deck for a copy of a board clear or target removal spell depending on the match up. I love it! And it will be great for the inevitable 3 cost spell that summons 3 of those Crystalline Oracles

Very strong card for Priest. Allows you to pull out Shadow Word: Pain or Shadow Word: Death if you need them, as well as Dragonfire Potion or Holy Nova for board clear. Think about it though: if you had only those spells in your deck plus Shadow Visions, you could literally pull up a strong answer card in nearly any situation just by using Shadow Visions...

Shadow Visions into Shadow Visions! I love it!

Oh you like to spend 2 mana for nothing?

Do it for the Yogg, bro.

You are basically doing the same thing as hero power oppnents face

That could combo with Gadgetzan Auctioneer, or a very hard counter to Millhouse Manastorm (win automatically with a card that gets buff whenever a spell is cast).

While this does help, still wish we had more ways of just going into Shadowform. 

The combo player in me really loves this though.

I can see this spawning 2 other degenerate combo decks either with 4x innerfire combo or 4x mind blasts. Pretty busted card with many uses imho.

I might run x2 Mind Blast, x2 Flash Heal, Embrace the Shadow, and this, giving me the 30 damage I need, with fatigue priest on wild. Prophet Velen for extra damage

And will end up with one in the hand anyway (second one must be in deck, and first 4 are used up already)

So you can have 4 Mind Blasts , oh boy some retarded combo may  be born here

Yep, Evolved Kobold might see play... Summon and buff it so it doesn't get killed, and then you have 28 damage from hand, 36 if you add Holy Smite

4 Purifys - New silence meta!

What happens when you cast it with less than 3 spells remaining in the deck?

The Same thing that happens when you discover with a drakonid Op when your opponent has less than 3 cards you will only discover from what remaining cards you have.Hope this helps

thanks

Better than Convert. In my opinion, it is going to be played only in specific combo decks or meme decks.
