Fan of Knives is a Rogue card, and apparently Rogue's are unplayable on Ladder, you shouldn't have to worry about running into them.
Ravaging Ghoul being used to kill your Panther is a net win considering how much damage a well timed one of those can do. I'd be happy if I got card parity out of that deal.
Maelstrom Portal is cast with some amount of Spellpower 90% of the time. yes, yes it can.
See, the funny thing is, you would have had a point if you were talking about Volcanic Potion (You know, stuff that's actually coming and will actually shape the metagame). But you're just another metagame sheep who thinks about what's being used, never why it's being used.
"apparently Rogue's are unplayable on Ladder"
You do know this is a rogue card......?
"Ravaging Ghoul being used to kill your Panther is a net win"
Ravaging Ghoul DOESN'T KILL YOUR PANTHER.
I was just tossing out a handful of the cards that deal one damage, not two. There's more. And, you know, hero powers that do 1 damage. I'd list them but you seem like the kind of person who had a comically bad rebuttal to everything. I bet you run Moroes too? Wouldn't want to be hypocritical after all.
Haha. there's an achievement for visiting the card page. This card man...
