New Warlock Spell - Impfestation

Now there's the Fel support we were waiting for. Is this actually good enough though? It's a pretty garbage card if your opponent doesn't go wide, in fact it does nothing if they don't have a board at all. This only makes sense if Fel Warlock somehow manages to turn itself into a tempo deck that relies on asymmetrical boardclears, otherwise this is just a worse Hellfire.

Its a situational card, and as such will likely never really see much play outside of discovers.

The main problem is obvious: its 6 mana, you don't get to choose what it attacks, and then its only ever powerful if your opponent goes wide.

The card may be situational but the upsides are great. Play this against any aggro tempo deck and instantly win. There's also Felwalker, which will cast this for free. That's something I guess.

Finally a good fel spell. Zoolock might use this as some kind of board refill in case they lose board, and control warlock decks could use it as a removal option. Seems like a good card, that worst case scenario will see play after rotation.

Isn't it basically offensive version of Spreading plague for Warlock. You get -2 hp and - taunt for +3 atk that attacks this turn.

This is pretty situational.  If you're playing a big deck (warrior and priest have had a few coming through the ranks), then this is just awful.  But against Pirate Warrior or Beast Druid before too many buffs get there, this could be decent. But for 6 mana... there are other cards that could be better utilized all around

Looks to situational ... could work as a refill for Zoo-Decks but otherwise i do not realy see this working out.

Maybe. I think in order to be good, as many imps as possible would need to survive attacking the enemy minions, and I'm not sure how often that would happen.
