It's not the worst idea in the world. I play a fair amount of control and vs. burn, swapping this for the 4th rev or 27th land seems fine. It's basically like a rev/aetherling split card since it does a duel job of giving you a stabilizer and finisher.Resolute Archangel is not remotely threatening for Burn, seriously... no one is siding in 7 drops against the least interactive aggro deck in the format.
Having said that, if I where the burn player, I agree that I wouldn't remotely care about this existing. You're either winning or losing based on the fights that happened before this and skullcracking this guy is infinitely more painful then skullcracking a rev.
