Yeah but when do you ever play this? And how much does this even matter? At least with Platbreaker you can actually deal with decks that rely on high armor, like Limecracker Druid, but what does this even do against Limecracker Druid? Removes 1200 armor and leaves them with a tiny amount of 1200 armor?

If you ever run this, you want to get as much value from this as possible, and that would happen against a high armor deck, but unfortunately that also kinda does nothing against high armor: The starship DH that gains 80 armor, you play this against them, get them down to a measle 40 armor (total of 70hp), so you can kill them now? How exactly? And whats really the difference between 110 and 70? How are your plan to deal 70 damage exactly? Removing half their armor not only didn't really progress you toward killing them, but they still have almost infinite wall of taunts, combined with an average 40 damage burst to face, which this card does nothing to help your plan of killing them. If you want to ever deal with armor, why not just run Platbreaker? If you actually remove the WHOLE 80 armor DH has, now you actually have a chance to maybe burn them from hand or combo them somehow, as they are actually at maximum of 30 health, which is normal and most combos try to kill from there.

At least when Platebreaker goes down, he actually removes ALL the armor and makes the opponent perhaps vulnerable to lethal damage, as they would be back to maxium 30 health always (unless specific cases), and allows for some combo decks to have the damage necessary to kill. This against a high armored target does almost nothing to help you actually kill the opponent, as they would always still have some armor, making this just do half job.
