Doesn’t work with spell dmg , but does work nicely with Shadowcloth Needle.
Probably not a spell I hard run in my Shadow combo/control Priest, but one I’m very happy to pick up from Wandmaker or Scorpid.
Actually Wandmaker becomes very nice in Priest decks now, with this card, Smite, Draconic, Flash Heal, the discover a dr card, mass silence that’s tradeable, nearly every card is pretty useful and Palm reading works very nicely with them all.
