How does a regeneration effect resolve when a permanent is selected?

A regeneration effect specifically allows a permanent to avoid destruction by replacing the destruction event with a regeneration event. When a regeneration effect resolves, it does not return the permanent to the player's hand, prevent future damage, or exile the permanent.

Instead, it effectively "regenerates" the permanent, which means that all damage on the permanent is removed, allowing it to survive an event that would normally destroy it, such as being dealt lethal damage or being destroyed by an effect. Additionally, the permanent will not tap unless stated by a specific effect; however, it is important to note that the regeneration effect includes a stipulation that if the permanent would be destroyed, it instead stays on the battlefield with no damage marked on it.

Understanding how regeneration works within the context of the game is essential. It reveals that while a permanent may be subject to destruction, regeneration can ensure its continued presence on the battlefield.
