Yes, as long as the first is destroying a card on the field.
For example, if Zaborg the Thunder Monarch was summoned, and targeted a monster, then the opponent could use his Stardust Dragon to negate Zaborg's effect and destroy him. Because this Stardust Dragon is also trying to destroy a card on the field, the turn player could use his own Stardust Dragon against it.
However, if the turn player used Exiled Force, then Stardust Dragon can be chained to this. However this Stardust will not be destroying a card on the field - the Exiled Force went to the graveyard as a cost. So a second Stardust could not stop the first in this case.
Stardust Dragon has a triggered effect that special summons it from the graveyard on the turn that it negated an opponent's effect. Forbidden Graveyard will negate this trigger, Stardust Dragon will not be summoned.
Yes. Gandora's Ignition Effect is a destruction effect, so you can chain Stardust Dragon to it, to negate and destroy it.
Yes it can. Sangan is a triggered effect, Stardust Dragon Assault Mode can chain to and negate it.
Because Dark End Dragon does not 'destroy' anything, Stardust Dragon is unable to negate it.
no it does not because stardust only stops effects that "destroy" a card(s) "remove" is different and therefore stardust cannot negate the effect Also you can get a card called divine wrath in a pack and negate it. - [Kaizoku] -Stardust Dragon/Assault mode can, Stardust Dragon can only negate destruction.
Yes. Most negation effects like Light and Darkness Dragon, and Stardust Dragon, can be used in the Damage Step, which is where Newdoria triggers. Stardust Dragon can indeed be used against Newdoria's activation.
Yes, if a card effect activating from the Graveyard will destroy a monster, Spell, or Trap card "Stardust Dragon" can be activated to negate the effect. Even though "Stardust Dragon" states that it destroys and negates cards, it can still negate an effect resolving in the Graveyard; the card in the Graveyard simply will not/ cannot be destroyed.
As a matter of fact, yes. The end of Anubis does negate Stardust Dragon's effect as long as he is on the field. Since Stardust Dragon's effect activates in the graveyard, and The End of Anubis' effect states "Monster cards that designate a card(s) in the graveyard or activate in the graveyard are negated."
Copycat has an effect that Triggers when it is summoned. Stardust Dragon Assault Mode can chain to this trigger to negate it, and destroy Copycat.
Yes it can if you don't activate Stardust Dragon's effect. But you can choose to activate his effect to Tribute Stardust Dragon to destroy and negate EHAZs' effect.
Stardust Dragon tributes itself as a cost for its own effect. So if Evolzar Dolkka chains its negation effect to this, Stardust Dragon can't do anything. Not only is it not there on the field for it to be tributed again, but Evolzar Dolkka isn't destroying a card on the field. The end result will be - Dolkka's effect will resolve, negating Stardust Dragon's negation effect. Since it's already in the graveyard, Stardust Dragon won't count as being destroyed, but that doesn't affect anything. The effect Stardust Dragon chained to will resolve as normal. Because Stardust Dragon's effect was negated, it will not resummon itself.
No, Stardust Dragon's negation effect is a spell speed 2 quick effect, which cannot be chained to a spell speed 3 card such as Solemn Judgment.
