Example:
Let's say a card named "Super Polymerization" is on the Forbidden & Limited List as "Limited 1". This means you can only have one copy of "Super Polymerization" in your deck.
It is crucial to stay updated with the current rules and regulations to ensure your deck adheres to tournament standards.
