create implication yu-gi-oh!_rush_duel -> yu-gi-oh!
While there are SEVENS and GO RUSH!! tags, the Rush Duel tag is, quoting the wiki, "applicable to a depiction of a Rush Duel exclusive duel monsters and cards." So this tag is for monsters and cards that don't necessarily appear in the anime, like how the duel monster tag usually used.
Edit:
Seems like it's indeed unnecessary.
