This is a request to add a GOAT specific variant for Nightmare Wheel due to following bug:
According to official GOAT rulings: https://yugipedia.com/wiki/Card_Rulings:Nightmare_Wheel
Nightmare Wheel" is NOT destroyed if the monster is flipped face-down. "Nightmare Wheel" continues to target the monster, inflict damage, and prevent the monster from attacking or changing battle position.
However, as of now, if a monster is being flipped face down due to a card effect, Nightmare Wheel loses its target and does nothing, see attached replay.
