Defang

In Commander, Defang punches above its cost because commanders are the most threatening creatures at the table and destroying them just sends them back to the command zone — Defang cages them on the battlefield instead, denying their activated abilities and combat presence without triggering command tax. In Pauper, it's a legitimate answer to aggressive creatures where enchantment removal is scarce, and the two-mana cost fits comfortably into control shells. Competitive formats like Legacy and Vintage have no use for it — those formats demand permanent answers or interaction on the stack, not a slow aura. Oathbreaker mirrors the Commander case: blanking a planeswalker's static effects isn't relevant, but locking down creature threats for two mana is a fine role-player in slower builds.
