Tag alias: yu-gi-oh! -> yuu-gi-ou
Reason:
The tag yu-gi-oh! reflects the oficial English romanized name: "Yu-Gi-Oh!", with hyphens and an exclamation point.
The tag yuu-gi-ou is currently being used. Compare with the original Japanese name: ้ๆฏ็.
(P.S.: There are many aliases already: yuugioh, yu-gi-oh, yu-gi-ou!, yu-gi-ou, yugioh!, yugioh)
