In Magic: The Gathering, what term for blocking was established in the Portal set?

The term "Intercepting" was established in the Portal set of Magic: The Gathering to refer to the act of blocking. This term was introduced to simplify and clarify the concept of blocking for new players at the time, making it easier for them to understand the mechanics of combat. By using the term "Intercepting," it conveys the idea that a defending creature is stepping in to intercept an attacking creature's intended target, preventing their attack from reaching its goal. This change in terminology helped streamline the game mechanics and provide a clearer understanding of the blocking aspect in Magic: The Gathering.
