Forum:Ancient Gear Beast Q

I'm a little confused by this effect: "The effects of your opponent's monsters that this card destroys by battle are negated."

To what extent does this effect go? I know it can stop the effects of flip effects of Morphing Jar but can it stop the effects of Wall of Illusions or D.D. Survivor? Can it also stop cards that activate in the graveyard such as Sangan and Witch of the Black Forest?
