Having a hard time meaningfully thwarting your opponent's plans is definitely a hurdle for the kind of swarm warband Edge of the Knife seems to want you to take - all those two-sword 1-damage attacks pile up. Or don't, I suppose. I think crewcut guy whose name I haven't learned yet was on to something using the deck with stormcast, although since I was using the Looncourt I couldn't really do enough damage to his guys to trigger the tempered state and let him get the most out of the deck.
Which makes me think of counterplay again - since he knew I had EotK too, he probably wanted to take down my two-wound fighters and leave the more-dangerous 3-wound fighters around, since they'd have been able to a) damage him and trigger tempered, and b) not easily use any of the tempered cards in my own deck. Instead he gibbed my boss and the squig rider right away, which meant I couldn't hurt him (but also... couldn't hurt him) but still left me some play with my little guys running around standing in meaningful places.
ETA: Yes, the ghouls not dying was definitely a bear to deal with. I even slipped into 1e thinking and assumed the bats couldn't come back but nope, it's everyone!
