The magic of Revenge of Ravens, just as it was with Ill-Gotten Inheritance, is that two minor synergistic effects are often better than one equivalent moderate effect. But if dealing lots of damage to your opponent is the goal, why on earth are you playing a four mana defensive enchantment rather than another creature? Effects like Blood Reckoning are especially suspect, since they only function if you’re pressuring your opponent’s life total. Tribute and Rhystic are great examples of why putting a card’s power in your opponent’s hands make them weaker. If it’s too painful for them to attack, they just won’t.
Rattlesnake effects are defensive cards which only function if your opponent cooperates by attacking you. But outside of Lost in the Woods, none of these cards were much good in draft. Other effects include Righteous Cause, Ever-Watching Threshold, and Teferi’s Veil, not to mention on-damage cards like Dissipation Field and Angelheart Vial. Hissing Miasma, Marchesa’s Decree, Blood Reckoning, Circle of Flame, Raking Canopy, and perhaps the oldest of them all, Barbed Foliage all punish attackers with damage, either to them or their controller. Magic has plenty of rattlesnake-type cards that discourage attacking.
