Edison-Accurate PSCT:
① Cannot be Special Summoned.
② While face-up on the field, this card is also DARK.
③ Once per Chain, if a Spell/Trap Card, or Monster Effect is activated (Quick):
This card loses exactly 500 ATK/DEF and that activation is negated.
④ If this card is destroyed and sent to the GY: Target 1 monster in your GY (if possible); destroy all cards you control, also, after that, Special Summon that monster (if any).
Edison Rulings:
● For the mandatory ③ effect to resolve, this card must be able to both negate the activation and also lose exactly 500 ATK and 500 DEF. If you can’t do either, you do neither.
● Vs Spirit Monsters, Lyla, Treeborn Frog, Vayu, etc:
These trigger effects will be negated by this card’s ③ effect, and can then trigger again.
(This can “loop” until Light and Darkness Dragon can’t lose any more ATK/DEF.)
● Summoning a monster with the ④ happens after cards are destroyed.
● The ④ effect will trigger even if Light and Darkness Dragon's summon was negated by a card like "Solemn Judgment".
