Which team would win, and explain why.
Arena: Ancient Egypt near the Pharoah's Throne
Restrictions: Since I'm not sure of Slifer and Diabound's speed, speed equalized. Diabound can only use attacks it started out with, not those that it copied throughout the anime. Magnamon is composite. Piedmon cannot turn Team 1 into keychains (Although I doubt it would affect Slifer.)
Please no flaming or calling others fanboys. Just enjoy and have fun!
