BUR #12593 has been approved by @evazion.
rename labyrinth -> labyrinth_(film)
rename labyrinth_wall -> labyrinth_wall_(yu-gi-oh!)
Two small but potentially confusing tags (no pun intended).
The first "Labyrinth" tag (which currently has only 1 approved post) is possibly a reference to the 1986 film of the same name. Since it's simply named "Labyrinth", I think a qualifier is needed.
The second "Labyrinth Wall" tag refers to a Duel Monster from Yu-Gi-Oh! which is literally a wall. I think a copyright handle is needed here as well.
