Let’s ask the obvious question first: how does this fare against Pacifism? I think it fares pretty well. Pacifism doesn’t allow for blocks or attacks, but it allows for things like Magmatic Force or Prodigal Sorcerer to wreak havoc during other steps whereas this card prevents that. However, Pacifism stops things like Ninjistu and cards like Strength in Numbers by denying the creature the ability to attack as well as removing a blocker from your battle calculations. Honestly, I might be tempted to pick this card over Pacifism in certain situations, especially when I’m going up against a deck that has a lot of ping effects like Goblin Sharpshooter. If you have the space, I’d recommend thinking about including a copy of this card in your deck alongside your Pacifism.
Pros: Prevents all damage that would be dealt by enchanted creature
Cons: Allows for blocks and attacks
