Hearthstone needs dual-targeting instead of a senseless new mechanic each expansion. It would open up so many possibilities if you weren't just limited to one target / effect. For example, cards like these wouldn't have to be random.
It's indeed a worse Deadly Shot. However, Warlock plays much more minions, so killing one of your own is not deadly for yourself. Especially with all the 1/1 you can summon.
This "fact" needs to die off. The times where warlock had readily access to tokens is LONG gone. You only have Forbidden Ritual, which no one plays and Possessed Villager as cards that produce a token. THAT'S IT.
As for the card itself is very clunky and VERY bad if you are behind without board. Even if you are ahead, Blastcrystal Potion is much better, even if it costs 1 mana more. With that downside, it should have cost 2. That would have been a fair price.
That is a card for a warlock deck that can dispense of some creatures. token/egg. But it is like with Sanguine Reveler , it needs more support from creatures you actually like to destroy or at least don't care.
I think people are underestimating this card. As a class that can play control you can very easily minimize the randomness involved (differently to Deadly Shot, where sometimes even a 1/1 hiding behind a huge taunt can represent a big problem for the Hunter) and you probably often have a few disposable minions to play this with (both in Zoo and in Control). Think about what happens after you play Nether Portal. You get two imps to sacrifice and since you never run out of them, sacrificing a 3/2 for a huge minion on your opponent's side of the board can be very good tempo-wise. On top of that you can play this with 1/1s, Mistress of Mixtures (and in general a lot of other 1 drops), any eggs you may run etc.
