so it doesn't die to Shooting Star or Cone of Cold or things similar to Arcane Missiles, but yeah, it's not an impressive buff. 

Lord Jaraxxus kinda Nemesis!

Maybe it's because it's the least risky to add?
Also they may have planned a bit of support in the next expansions but this is a long shot.

Too bad I just opened it, still, great core card for everyone. Random legendaries are the best for the people who start playing, hope I had this kind of cards when I started playing.

Too bad I don't think this will see play anyway haha, still, was always a fan of the card.

Been playing this card since day one, but I was hoping it was going to get some kind of change like Lightning Storm though not sure what I would like.

Thank god they didn't rotate this, I play 2 in every control warlock so far (not highlander ones of course). Great card and still one of the better animations in the game.

Oh boy, time to save the Oozes again for the late game. Really really happy about the 15 life change.

Penance is great, and warlock cares more for healing than priest so yeah, way better here. I gues the only difference between the 2 cards now is that this is a shadow tribal card.

I've still played this in some wild control decks, really happy to see it back and with the keyword buff, even if you can no longer get the spell damage totem for it.

For me if feels so weird that this is staying and Polymorph isn't. At least both classes still have Devolving Missiles which in most situations it's better than both.

I always liked this card, mostly because of the artwork and creature itself. I hope a value oriented paladin deck ends up being good and this finds a place there.

If pure paladin is still a thing when the next season starts I think this will find a place since it'll need more class cards to fill the gaps since there will be 2 less sets.

I honestly don't know if this is sarcasm or not. I do honestly love this card and love to see it back.

I really don't like Flamestrike artwork, I was hoping since this is part of a new core set that it could have changed. Nevertheless, good buff, always a fan of the card and the effect.

Demon Hunter's best BattleFriend.

mmm I don't see it, though talking about artwork, I would have liked that some of the remaining cards, specially the old ones, had new artwork for the core set, like Flamestrike for example.
About the Crimson Sigil Runner it good that aggresive DH decks will still have this tool, not broken, but not total crap.

Now that Skull of Gul'dan rotates this may see more play, but then again, I think DH still has better draw options to choose from.

For some reason I see this as the Power Word: Shield of DH. The pre-nerf one I mean.

You are right, it does have that "Core" flavor to it.
