Battlecry: Deal 5 damage to your hero. If you have 2 mana minion in your hand, repeal the battlecry.

Pit Lord will still be that good card in many warlock decks.

Because of it's good body in one minion for 4 mana.

How about Skull of the Man'ari or Possessed Lackey?

ok but then you just get a 5/6 demon, which is not bad but might take space in a deck which doesn't need an additional body. Doomguard is always played with skull because it has charge, and Voidlord is played because it can be very annoying to remove from board. I don't think there are still good enough reasons to play this card.

I feel like he'd be much more playable if he was a 5/7 because that one extra health would make him MUCH more sticky.

He'd be able to make favorable trades with nearly all 4 drops and most 5 drops and, without spell damage, only Flame Lance, Forbidden Flame, or Pyroblast would be able to 1 shot him.

Has someone tried this in a Demon Renolock?

Yes my friend, and i have to say that it is compatible with the deck, i like it :) 

Pitlord, what have they done to you!

 Violet Illusionist

Yes, but it's a 7 turn combo (when 5/6 stats instead of 4/5 doesn't make really a difference), or you have to pray that the illusionist will survive turn 3. Anyways, +1/+1 for 5 damage isn't worth it in my opinion.

BIG flame imp ;)

Quote from Bencur >>

It would be soo much more useful with a Battlecry: Discard a random card instead of 5 damage.

Not since Kara it isnt. like a succubus gets +1/+1 for the discard, so would this, and since Kara, Combined with Silverware Golem, Malchezar's Imp and Tiny Knight of Evil, Succubus is pretty good.

EXPLAINING THE JOKE RUINS IT 

leave and never return

Someone played this when I am playing a rogue. I sapped it back to his hand. He summon it out again and seems very insistence about having him on the board.

SMorc

and unlike chillwind yeti, this is a demon. which is why I think he'll fit nicely in my demonlock deck :D
