The first time Odd-Eyes Rebellion was summoned it changed the weather in the Action Field from a clear day to stormy. This time its power output cuts out all the electricity in the surrounding city. That’s one rather powerful dragon!
Yuri looks so annoying that they think he could make a mistake.
And this is kinda one of the more unique duels in YGO history. While characters being forced to use new decks isn’t unheard of, it is new to have a character, a villain no less, to actually take time to read the cards and wonder what to do instead of know what to do right away.
