Forum:Stardust Dragon Family all on the field!?

What cards will I use to destroy these monsters on the field of my opponent: Stardust Dragon, Stardust Dragon/Assault Mode, and Majestic Star Dragon. You see his using his best deck. I was using my psychic deck. I already completed all psychic monsters, spells, and trap cards. Please tell me what good combos will I use to defeat or even prevent his summoning of Stardust Dragon. Thanks.
