Regeneration

Cards built around the legacy regenerate shield, which replaces a destroy event with tapping the creature, removing it from combat, and clearing damage. Includes creatures with the keyword like Lotleth Troll and Thrun, the Last Troll, mass regenerate spells like Wrap in Vigor, Auras and permanents granting the ability like Trollhide, Asceticism, and Yavimaya Hollow, and modal options like Golgari Charm. Distinct from protection.protection_spell, which covers instant-speed grants of indestructible, hexproof, phasing, or protection-from-X rather than the regenerate replacement effect specifically.
