yes, which is why people thought he will also use No. 40, 50, 60, 80, and 90, maybe 100 as well
But nope, 40, 50, 70, and 80 belonged to someone else, 60 and 90 are game original despite 90 being a Galaxy-Eyes, and he won 100 but only hold it for a few minutes before having to hand it over
Well for one that depends on how you define ace. In Yugioh it means his signature card not necessarily his most powerful. Why Neo Galaxy Eyes Photon Dragon is arguably his strongest card, Galaxy Eyes Photon Dragon is generally considered his signature card.
