Its main problem is that it's obscenely worthless against any form of aggro, and that shit just doesn't fly on the ladder. The obvious comparison is BGH who you can play on curve just fine while Rend is completely and utterly dead for the entirety of the match, which is particularly hurtful vs aggro where every early draw matters. The meta would have to make an unprecedented shift towards control to ever justify including this card.
Why is it obscenely worthless against any form of aggro? Even mech mage runs dr. boom and antonidas. Only against face aggro and who can say their entire deck doesn't have more than a few cards that is bad against aggro?
I think you're being a little bit silly tbh. Having a very strong anti-control card in your deck can actually help your deck focus a bit more on aggro since you've already got a strong leg up against control.
People are always surprised when mind control works in priest, despite it being heavy aggro and it really doesn't matter. You can't built your entire deck to be anti-aggro, just isn't worth it because the meta is never that heavy on aggro, despite people's perceptions.
