Regeneration

Cards that establish regeneration shields, the legacy effect that replaces the next destruction of a creature by tapping it, removing it from combat, and clearing damage. Includes mass shields like Wrap in Vigor, self-shielding bodies like Lotleth Troll and Thrun, the Last Troll, granted abilities from Auras such as Trollhide and Skeletal Grimace, and land-based shields like Yavimaya Hollow. Distinct from Protection Spell, which grants hexproof, indestructible, protection, or phasing rather than a regeneration shield, and from Fog, which blanks combat damage for the whole turn instead of saving one creature.
