Limitation text

Limitation Text is the name given to the text sometimes displayed in the bottom-left of a card, which is used in lieu of a Card Number, and details special limitations for when that card may be used.

There are currently four types of text used.

This card cannot be used in a Duel.
This is to date only used on the Egyptian God Cards and for the Match Winners series. It lets the user know that they are only not allowed to use the card in a Duel.

This card cannot be used in a Deck.
This is used on all release Token Monsters. This states that the card in question cannot be used in either the Side Deck, Main Deck or Extra Deck.

Not usable in Official Duels.
To date, this is only used on "Get Your Game On!". This states that the card in question cannot be used in Official Duels (i.e. Duels in Events Sanctioned by Konami or Upper Deck Entertainment), but can still be used in Casual or Friendly Duels.

Not an Official Yu-Gi-Oh! TCG Card.
"The Seal of Orichalcos's" Limitation Text states the card is not an Official Trading Card Game card, therefore the card itself is stating that it is illegal, but was specifically made and used at the Duel the Master 2005 Event, hosted by Upper Deck Entertainment.
