One of The Undertaker's staples over the years has been causing a blackout in the arena and magically appearing in the ring when the lights come back on usually confronting (and then beating up) a terrified foe. The problem with the trick is its transparency we know Undertaker is hiding under the ring or running out from the back, and the lights are off for long enough to allow him to make whatever movements he needs. Still, it never occurs to his flustered opponent to try to leave the ring, so it can't be considered a poor battle tactic. Perhaps that's why the Wyatt Family has adopted it. To be fair, it works better on a taped show. On Smackdown (where the Undertaker competed for nearly the entirety of the brand split), video editors can cut down the length of time the lights are off, making it seem as though Undertaker really does materialize in a fraction of a second. And, no matter how long it takes, the fans pop when the lights go off in the end, you can't argue with that.
