How do you get the field spell zombie world in Yugioh 5ds?

You can't get "Zombie World" in Yu-Gi-Oh! 5Ds. Here's why:

* "Zombie World" is a card from the "Yu-Gi-Oh! GX" era: While the games are connected, the card pool for each series is different.

* Card availability is tied to the era and its sets: "Zombie World" is not included in any of the sets available in Yu-Gi-Oh! 5Ds.

To get "Zombie World," you would need to play a Yu-Gi-Oh! game set in the GX era or later, or use it in a custom deck.
