So prevent 6 and heal 6 for 2mana. Pretty good.

Actually, it may prevent more than 6. 

This is actually a highly potent tool for keeping you alive.  It will prevent significant damage and perhaps healing you by a lot as well.

Bloodbloom can maybe comeback with good combos with this card but it just looks like a bad card to put

Edit: They literally nerfed immune this won't work anymore

Sadly it cost 4

I mean luckily hahah

Will probably be a Warlock staple just for the Life Tap synergy. Incidentally, it also counters MC Blingtron, and can be used to prevent fatigue, or be used alongside cards that deal self-damage, like the Movement of Wrath.

Super nice, now I can't die for massive fatigue damage in 3 turns :).

Equip this for ANOTHER 3 turns.

PLay the 4 4/2 pirate FOR ANOTHER 3 TURNS XD!

then play THE SAME PIRATE FOR OTHER 3 TURNS!! HAHAHAHHAHA! WHO WILL DIE FASTER BUDDY?

Does it also stop the fatigue damage ramp up?

No, fatigue isn't depending on taking the damage but the amount of cards you have drawn with an empty deck.

Nice one. And as a bonus it counters curses as well.

Does this work with the other fatigue cards? The wording makes it seem it would not, but it has to, right?

The harp is for the self-fatigue cards, which actually look pretty good - especially as they synergise with the Nathria implock stuff that's so strong.

Six turns of fatigue damage.

looking at warlock and warrior cards u cant tell me blizz isnt pushing us to play certain classes.

At its worst, this is a 2 mana, negate 3 hero powers and restore 6. If self-damage becomes big this year, then this could potentially negate more. Hell, that legendary card has a deal 6 to everything which this negates the face damage.

This will replace Mistress of Mixtures for warlock

At worst: 3 mana, heal 12
(Life taps)

Correct me if I'm wrong, but it would technically be 12, as you don't lose the 2Hp, and also heals 2 per durability, which does look pretty good!

You're right, I was thinking 12 before I typed it. Then I lapsed thinking how someone might forget the "6" you also negate from the taps.
