Nahiri's Binding

White's answer to the threat that outsizes its removal, or the planeswalker its deck has no clean way to touch. Rather than kill the body, this Aura reaches under it and disconnects it from the game state: the creature stays on the battlefield but no longer attacks, no longer blocks, and no longer taps for whatever activated ability made it dangerous. Shutting off those activations is what separates this from a plain Pacifism variant. Pacifism and its cousins have always left utility creatures free to keep ticking their abilities; this closes that door too, and it does the same job on planeswalkers, whose loyalty activations are the only thing they exist to do. Point it at a planeswalker and the card is effectively frozen in place: it sits there accruing nothing, unable to defend itself, waiting to be ignored. The cost of that reach is the cost of every Aura. It grants no card advantage, and any bounce or blink on the enchanted permanent frees the threat while leaving you down a card. So it answers a wide slice of problems that color-appropriate removal often cannot, at the price of the fragility that has always kept enchantment-based removal honest.
