Warlocks like hurting themselves so this should be pretty easy to upgrade. Even if this didn't have lifesteal I think it would still see play.

Warlock card in next expansion, life steal deal 8 damage to a minion.

Its a stong card with nice art, Its just a pet peeve of mine that a same card concept for the same class in back to back expansions

Finally, another card besides Floating Watcher that has self-damage synergy! And here I thought Blizzard had forgotten about it.

Works well with the warlock legendary cause u can get those seals open faster via bloodbloom or cho'gal and this card helps u keep up with that heath loss.

Wrathguard

The fact that with the lifesteal mechanic you gain the full healing even if the minion targeted has less than 7 health is huge. This card gives warlock consistent healing in the late game; even at one upgrade it's an extremely cheap Holy Fire

Definitely it's great card, but Holy Fire can go face, this can target only minions.

the cost of going face is evaluated at approximately 1 mana. Therefor this card at one upgrade is still about 1 mana cheaper than standard value.

Thanks for the input and example; so maybe at one upgrade this card is just fair then and not a super good deal. Either way though I'm a fan of it :)

How does it interact with the Bloodbloom? It probably activates the card, right?

And there is one more question about Bloodbloom as well. If we play Bloodbloom+something and then we played it we probably get the upgraded version of this card. But what if we play Bloodbloom plus this card? Would it be enough to get the upgrade? HS interaction thinkers, get on!

Going to be really easy to upgrade, but at that point you may as well just run Blastcrystal Potion

since when does Blastcrystal potion heal you for a substantial amount while also not nuking your mana?

- removal : check
- has synergies with warlock natural masochism skill : check
- HEALS YOU! : it's like Gul'dan stole the christmas

This card was super meh, and then those other two reveals. Wow. I love this set.

do we actually know whether the spellstones need to be in hand to be upgraded?

Yes they do. It's been confirmed.
