Regeneration⁣ - Revised⁣ (Common)

Regeneration is a green Aura from the Revised Edition that enchants a creature, allowing you to spend a green mana to regenerate it. This means that if the enchanted creature would be destroyed, it instead survives by tapping and removing it from combat, making it a great defensive tool. It's particularly advantageous in decks that rely on creatures with high toughness or those that can be targeted frequently, providing a reliable way to keep your threats on the battlefield.
