Light and Darkness Dragon
① Can't 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.
② If this card is destroyed and sent to the GY: Target 1 monster in your Graveyard (if possible);
destroy all cards you control, also Special Summon that monster (if any).
● For the mandatory ② 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 Spirits/Lightsworns/Treeborn Frog:
These trigger effects will be negated by this card’s ② effect, and can then trigger again.
(This can “loop” until Light and Darkness Dragon can’t lose any more ATK/DEF.)
● Destroying and Summoning are simultaneous.
