Protective Response saves a permanent from destruction for a single white mana at instant speed — clean, cheap, and immediate. In Kasla, the Broken Halo decks it doubles as a damage-dealing trigger rather than sitting as a pure reactive tool, which is what separates it from most other protection spells.

Kasla, the Broken Halo
Kasla, the Broken Halo converts each instant and sorcery cast into a damage ping, so Protective Response pulls double duty — it protects a key permanent while simultaneously advancing Kasla's damage-dealing engine for one mana.

Protective Response is legal across every major constructed format, but it sees virtually no play outside Commander — narrowly reactive spells need consistent threats to protect, and Commander supplies those in abundance. In Commander specifically, the card earns its slot in any white deck that wants cheap, stackable protection, and it's near-automatic in Kasla, the Broken Halo lists where the spell's damage trigger is as relevant as the protection itself. In 60-card formats, better single-target protection exists at the same or lower cost, so Protective Response sits firmly on the bench.

Price Context
Current price
$0.10 bulk tier
At $0.10, Protective Response is bulk in every sense — grab a copy without thinking twice. Bulk rares occasionally spike when a commander breaks them, but a narrow protection spell is unlikely to move meaningfully off this floor.
