Light and Darkness dragon

I'm wondering because his effect makes him dark, but then he would be negated so hes not dark anymore, so hes not negated which makes him dark again.. at least that's what I think

What will happen is whenever LaDD would chain to a Spell/Trap or Monster effect to try and negate it. When LaDD's effect goes to resolve, SIM would see that LaDD is DARK and say "Hell no!", then negate LaDD's effect.
Since SIM is also a continuous effect. It basically means LaDD will be unable to negate anything. EDIT - If LaDD then dies and activates his other effect, since he isn't face-up on the field anymore, he isn't DARK so SIM can't negate his graveyard effect. Light Imprisoning Mirror would negate both his effects. That's what I get for answering rulings at 4am, a mistake

However if you activate bottomless or prison on ladd then chain the mirror to his effect it will negate his effect then your prison or bottomless will remove him anyways. Abusing his once per chain effect is the best way to nail him.

Ladd as three effects and one restriction. It can't be special summoned.

It's first effect is continuous. It is treated as a dark monster while it is face up on the field. Continuous effects do not activate and they do not start chains. They are simply always in effect. Shadow mirror negates the effects of dark monsters once they activate. Since this effect never activates it is not affected. Now for the second effect.

His second effect will be negated because he is treated as a dark monster. Therefor every time he goes to reduce his attack and negate your card he is negated by mirror. No atk/def reduction and no negation.

His last effect activates in the graveyard. Now his first effect which makes him a dark attribute monster isn't active since he is no longer on the field. So he is only a light monster now. So his 3rd effect of destroying your cards and special summoning slips by the shadow mirror.

Understand?
