As long as that Stardust Dragon had been special summoned properly by Synchro Summon (ie, it did not reach the field via Starlight Road), then the opponent is free to Monster Reborn it before it tries to special summon itself in the end phase.
Yes. Stardust Dragon itself is a monster, there is no requirement for the opponent's destruction effect to try to destroy an 'other' monster, just one that tries to destroy Stardust Dragon itself will do.
Yes. Absolute Zero destroys cards on the opponent's side of the field, so would be trying to destroy, at the very least, the Stardust Dragon in question. It can therefore be tributed to negate the effect, but won't apply a destruction effect to Absolute Zero since he is already in the graveyard.
If an opponent activates a card effect from their hand, "Majestic Star Dragon" can negate and destroy it. For example, if your opponent activates the effect of "Honest" from their hand to boost their monster's ATK, you can chain to the effect with "Majestic Star Dragon" to negate and destroy "Honest" and its effect.
The only time you can ever tribute something you do not control, is if a card specifically says so. Lava Golem lets you tribute the opponent's monsters, and Soul Exchange can let you do so too. However if there is no text like this, then the tribute must come from amongst monsters you control.
Yes because it's effect says you can summon a normal dragon type monster from either players graveyard. So since tribute to the doom destroys the monster is effect activates.
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.
Stardust Phantom's first effect is a Trigger, and will activate whenever the condition is met. That means it can activate in your turn or your opponent's turn.Stardust Phantom's second effect is an Ignition Effect and can only be activated in your own turns. The protective effect it applies to a Synchro Monster will work like a continuous effect, it can be protected once per turn in either player's turn.
You can tribute this card to negate the activation of Spell Card, Trap Card, or Effect Monster's effect that destroys a Card (s) on the field and destroy that card. If you negate an effect this way, you can special summon this card from your Graveyard during the End Phase
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.
Even though Earthbound Immortal Cusillu can not be attacked by the opponent, the controller of this monster can attack an opponent's attack position monster.After attacking with Cusillu and calculating any damage you receive in battle, you may tribute another monster you control and reduce your opponent's Life Point in half. This all takes place during the Damage Step and the tribute is treated as an effect, not a cost.
No part of Call of the Haunted's activation prevents monsters from being tributed. Of course, if you activate it in your opponent's turn, you could only tribute the monster for a spell speed 2 effect or trigger.
Your opponent gets the effect.
