Which of the following is NOT a condition that determines if an effect "depends on" another?

The correct choice highlights an important aspect of how effects interact within the rules of Magic: The Gathering. When determining if one effect "depends on" another, the interactions between those effects are critical to assess how they impact gameplay and card functionality.

The condition of being in different layers is significant because effects that are applied in different layers do not influence one another directly. Effects are resolved in a strict order defined by the layers of the comprehensive rules, where certain types of effects are handled before others, leading to a clear separation of their impacts. This means that even if two effects might interact conceptually or thematically, if they fall into different layers, they do not depend on each other for their resolution.

In contrast, changing the text of each other, being from different sources, or the sequence of their application can create dependencies where one effect directly influences the outcome or functionality of the other. These factors indicate a direct relationship between the effects, where the resolution of one may directly alter how the other is interpreted or functionally applied, thus establishing a dependency.

Recognizing that effects in different layers do not create a dependency is crucial for accurately determining how card effects interact in a game. Understanding this distinction helps players and judges navigate complex game situations efficiently, ensuring that
