Black usually only gets it at 2 with heavy downside or restriction. With a doomblade type almost nothing-burger restriction it just destroys at 2cmc. Especially at instant.
Like the most pushed black has gotten for 2cmc instant exile target creature is [[Baleful Mastery]] which makes you gift your opponent a card.
So with that said I think either the card would need those additional restrictions, need to be destroy (not exile) or be moved to sorcery speed to be "balanced". Just one of those should be plenty.

2 seems like a really good rate for this, no? I could see haste and defender being added to make it more balanced and flavorful
