As an exercise, I'm attempting to derive deck designs for Zexal characters as they would be near the start of the XYZ era (assuming that card release order was mostly like our own). Manga villain Kyoji Yagumo is known for his signature Spider and Underworld cards, but as he's only seen Dueling late in the series, we have no evidence he had all of those cards back when he was participating in tournaments long before Yuma's story started.
As part of the exercise, this deck uses no cards from later than Generation Force. But if anyone has any thoughts about other cards or strategies better suited to the era, or sees something else I missed, feel free to comment. Remember that Synchros are unavailable, as Zexal tries to pretend those don't exist.
