Edison-Accurate PSCT:
① If the effect of a DARK monster is activated on the field/GY, negate that effect.
Show/Hide Modern PSCTEdison Rulings:
● This doesn't stop monster effects from activating.
It just negates any effect which does activate (on the field/GY).
● Even if the Physical card is no longer on the field/GY, the effect is still negated.
If the monster is face-down when its effect resolves, the effect is still negated
