I'm thinking about this with Radiant Elemental and it seems like complete aids.
One of the other revealed priest cards is Animate Dead. 1 mana shadow spell that resurrects a minion that costs three or less. If you've had a radiant die already, you can go radiant + animate + animate and now your vision of darkness costs 0. So you can grab a ton of removal spells that also don't cost anything, as well as more animates so you can summon three more radiants next turn and run it back. Infinite removal and lifesteal spells, plus you eventually get enough Void Shards to just kill the opponent. I can't think of anything that beats this besides a straight otk. And you can tutor the radiants and Svalna with Switcheroo.
The only wrinkle I can see is if your opponent doesn't have minions to remove a good portion of the shadow spells are dead in your hand and hand space might screw you or at least slow you down. Also Theo stealing visions, but you can build a nest egg of Identity Theft's as you discover and maybe steal it back.
Someone please tell me the obvious reason this doesn't work. I really want to hear it.

Is it "Steal" or just a copy?

I already hate this card
