It also costs (1) if you Illuminate it

I am starting to think that between this, Animate Dead and Bonecaller, Scourge Rager might be a viable card for priest.

all these support for a 3.5 mana value card

Bananas card. Cheap enough that you can just sit on it and cast it whenever without disrupting your curve significantly, even if you run relatively few undead.

good for aggro undead priest

also, a shadow spell, which means you can mix it with shadow package

Well I mean, it's insanely strong.

Depends if ur deck has lot of undeads

Jesus Christ... Priest has crazy good card draw these days which from the beginning was one of their Class negatives andr drawbacks...

Kinda wished it drew undead minions, it fits the name and art, and it would make a little more consistency for the deck with chaining undead payoffs, like this one.

Nevertheless, still pretty good if aggro priest can come back into the meta and if it does, this will be a staple

turn 1 drop undead when you have 2 of these in hand, then you will draw 4 cards on turn 2

That would be an insane cycle play. Too bad it relies on your opponent killing it on their turn. I can imagine people will be hesitant about the insta kill of a minion now that they see this card. I for one will be reconsidering early game strategy against priests now. This card is 5/5 for sure. Well balanced.

Too bad it relies on your opponent killing it on their turn

Well, if your opponent has a minion (and no Freezing Trap in play), you can simply kill your 1-drop by attacking theirs and activate the effect. "After your last turn" might be activated this turn, too, if you kill your minion on your turn.

Cost (2) if you have a shadow spell on hand , would be sexy

that would mean it is a good control card too but Blizz does not want that this only fits into aggro trash and this is deliberate design choice
