Ensure Stardust Dragon's return

"Stardust Dragon's" effect is very powerful. You can Tribute it to negate any effect that would destroy cards you control and then "Stardust Dragon" is Special Summoned back to the field during the End phase. But if your opponent removes "Stardust Dragon" from play before the end of the turn it would never come back! Protect your Dragon from any remove from play effects with "Imperial Iron Wall"! This will also protect your cards on the field from remove from play effects "Stardust Dragon" couldn't negate.
