After effects have been applied, what is the final status of a creature that had its abilities affected by multiple layers?

The final status of a creature that had its abilities affected by multiple layers reflects the cumulative effects of those changes. In the context of Magic: The Gathering, the layering system is essential for determining the outcome when multiple effects are applied to the same aspect of a permanent, such as a creature.

When multiple layers interact, the effects applied in higher layers take precedence over those in lower layers. The result is that the creature's abilities or characteristics will be modified based on the most recent and relevant effects from the top layers downwards. This means that if layers contributed different changes to the creature's abilities, the final result will be a combination of all applicable effects, rather than just retaining its original abilities or reverting to any previous state.

This cumulative nature allows for a dynamic interaction where abilities can stack and interact in complex ways, providing a rich and strategic gameplay experience. Thus, option B accurately describes the final state of a creature after multiple layers of effects have been applied.
