Here's why:
* They are immune to destruction by card effects: Egyptian God Cards have a built-in effect that makes them immune to being destroyed by card effects. This includes effects from monster cards, spell cards, and trap cards.
* They can only be destroyed by specific means: Egyptian God Cards can only be destroyed by specific means, such as:
* Battle: They can be destroyed by attacking them with a monster that has a higher attack power than the God Card.
* Specific Card Effects: Certain cards specifically designed to destroy God Cards, such as "The Seal of Orichalcos".
* Their own effects: Some God Cards have self-destructive effects that can be activated under specific conditions.
Therefore, the effects of monster cards cannot directly destroy Egyptian God Cards.
