Mistborn Protector (3)

About Mistborn Protector (3)

Mistborn Protector (3), defense reaction, designed by None first released in February 2026 in the set Compendium of Rathe. It's currently being selled by the minimum price of 1.51.

Mistborn Protector (3) fits best in decks that frequently **create tokens or other cards during the opponent’s turn**, such as heroes that generate Ash, Gold, Silver, Auras, or other token permanents at instant speed, because it can defend for 4 instead of 3 when its condition is met; however, as a 3-cost defense reaction, it competes with generally stronger red defense reactions like **Sink Below (red)** or **Fate Foreseen (red)**, which cost 0 and defend for 4 with useful filtering or deck manipulation, making them far more resource‑efficient in most builds. Unless your deck reliably creates cards on the opponent’s turn and specifically wants extra 3-cost blues for resource density, Mistborn Protector (3) is usually outclassed and would not commonly see competitive play compared to cheaper, more flexible defense reactions.
