Unfortunately, there is no way to obtain the Egyptian God cards in that specific game. The game's content focuses on the "Arc-V" era of the anime, and the God cards are not part of that storyline.
Here's what you can do to get the God cards in other Yu-Gi-Oh! games:
* Yu-Gi-Oh! 5D's World Championship 2010: This game allows you to unlock them through the story mode, where they are tied to the ancient Egyptian storyline.
* Other Yu-Gi-Oh! Games: Many other Yu-Gi-Oh! games, particularly those based on the original series, allow you to obtain the God cards through gameplay, trading cards, or special events.
If you're looking for ways to get the God cards in a game, it's important to check the specific game you're playing and see what its mechanics are for obtaining those powerful cards.
