Here's how it works:
* Normal Summoning and Setting: This card cannot be summoned to the field in the traditional way. You cannot use your Normal Summon for this monster.
* Special Summoning: This card can only be Special Summoned through the specific means mentioned in its text. For example, if the card states "This card cannot be Special Summoned except by the effect of a "___" card", then you can only Special Summon it if a card with "___" in its name has an effect that allows you to do so.
Important Note: The monster card's text must be carefully read. Some cards might have alternative conditions for Special Summoning, such as:
* From the hand: Some cards can be Special Summoned from the hand, either at the cost of specific resources or through a specific effect.
* From the graveyard: Certain cards can be Special Summoned from the graveyard, usually under specific conditions.
* From the banished zone: Some cards can be Special Summoned from the banished zone, often with unique requirements.
Example:
Let's say a card reads: "Cannot be Normal Summoned/Set. This card cannot be Special Summoned except by the effect of a "Spellcaster" card."
You cannot summon this card using a Normal Summon, but you could Special Summon it if a card with "Spellcaster" in its name has an effect that allows you to Special Summon it, like "Spellcaster of the Forbidden Spell."
Remember, always carefully read the text of monster cards in Yu-Gi-Oh! to understand their summoning restrictions and how you can bring them to the field.
