Forum:Majestic Star dragon vs Divine Wrath

Me and my friend had a arguement over this in 3rd period today at school, Majestic Star Dragon can negate the effect of any card once per turn, but Divine Wrath would stop it's effect and destroy it, but Majestic Star Dragon's second effect comes up and destroys every card on my opponites side of the field if it threatens any monster card of mine (I think that is right) and it's self bring Stardust dragon out at the end of my turn.

I don't know if this is right, I also don't know what would happen so can someone check this ruling for me?
