What is the third sublayer of layer 7 dealing with continuous effects?

The third sublayer of layer 7, which deals specifically with continuous effects that modify power and/or toughness without setting a specific number, encompasses effects such as those from Anthem effects or similar modifiers. These are effects that impact the creature’s stats but do not create a fixed value; rather, they function by modifying the existing values dynamically based on other influences in the game.

For example, if an effect states that a creature gets "+2/+2", it modifies that creature's current power and toughness by adding 2 to each, allowing it to adapt based on other existing stats or modifications. This is different from effects that would set power and toughness to specific values, which are treated in their own sublayer. Continuous effects in this specific sublayer are crucial for understanding how various ongoing modifications interact, especially in complex scenarios with multiple effects acting simultaneously.
