Where can you find a duel terminal?

It seems you're asking about a "duel terminal" in the context of something like trading card games or perhaps a video game.

To help me understand what you're looking for, please provide more information:

* What kind of game are you referring to? (e.g., Yu-Gi-Oh!, Pokemon, Magic: The Gathering, etc.)

* What is a "duel terminal" in this context? Is it a specific piece of hardware, software, or a feature within the game?

Once I have a clearer understanding of what you're asking, I can provide more helpful and accurate information.
