(1) When this card is Normal Summoned, you can Special Summon 1 Level 2 or lower monster from your GY in face-up Defense Position. That monster's effect(s) is negated.
The (1) optional Trigger Effect activates in the Summon response timing (like Trap Hole).
This effect targets a monster in the GY. It is negated by Necrovalley.
This effect only negates the target's effects that activate on the field. It can still activate its effects.
If the target is flipped face-down / leaves the field, its effects are no longer negated.
This effect can't activate if Junk was Normal Summoned as Chain Link 2+ by Ultimate Offering.
If the monster Special Summoned by "Junk Synchron" is flipped face-down and then face-up, its effects are no longer negated.
If you Special Summon "Nimble Momonga", its effect will activate when it is destroyed by battle and sent to the GY. If you Special Summon "D.D. Scout Plane", its effect will activate when it is removed from play.
If you Special Summon "The Calculator" with "Junk Synchron", you can activate "Inferno Reckless Summon" because the effect of "The Calculator" is negated and its ATK is 0.
If you Special Summon "Hand of Nepthys" with the effect of "Junk Synchron", when you activate the effect of "Hand of Nephthys" it will be negated, even if you Tribute "Junk Synchron" to activate the effect.
