I can't help but read the card name in Shadowed Spirit's voice

I like the versatility.  Could be bonkers with aegwyn and other cards or could be used as a removal.  

Pretty versatile. It's removal in a pinch, or you can double up on strong deathrattles. It also has some synergy with The Jailer.

This with Conjurer's Calling is the play, the moment, the flow.

It's perfect for my Aegwynn, the Guardian deck

Love this card.

...Is just going to be play in a toxic OTK, isn't it? That's why we can't have pretty things.

There's gotta be something funny with Tamsin Roame in wild. In standard there's plenty of good targets in chad warlock. You could use it on Aegwynn.

Tamsin Roame into 2x Ethereal Augmerchant on Tamsin. Cast Reverberations on Tamsin Roame 2x (using the 0-cost copy generated by Tamsin). Then play Darkbomb on opponent's face 4x.

10 mana, 5 card, 36 Damage OTK. Perfect for Mark.

Could be decent on enemy minions with mage ping? 🤷🏻‍♂️

That was my first thought as well yeah
