* Sacred Cards are a separate game: *Yu-Gi-Oh! Sacred Cards* is a standalone game with its own unique rules and mechanics. It doesn't directly use the same card pool as the traditional *Yu-Gi-Oh! Trading Card Game* (TCG).
* Ra is not in the Sacred Cards set: "Winged Dragon of Ra" is not one of the cards included in the *Sacred Cards* set. This game features a smaller, specific selection of cards from the TCG.

Important Note: "Winged Dragon of Ra" is not a readily available card in the modern TCG. It's a very powerful card, and it's only found in older sets. You may need to rely on specific trading or purchasing methods to obtain it.
