Forum:Stardust vs royal oppression

player A has stardust dragon on field, and player b has royal oppression activated.

player A activates monster reborn to get a monster from graveyard, and player b activates royal oppression's effect, pay 800 to negate the summon and destory it.

At this instant, Can player A tribute stardust to negate the activation of royal oppression and destory royal oppression?

One extra question, about new card, Jurrac Herra, when I destroy Jurrac striko, and opponent special summon herra from graveyard, and I activate royal oppression's effect to negate it and destory it, can herra be re-special summonned chaining to the destruction of striko at the point? my friend say it is possible since it negates the summon, but doesn't the chain resolve and herra goes to graveyard which wouldn't let herra to be re-special summonned?
