I'm watching 5D's and I'm to the finals of the Fortune Cup and this question popped into my head.

Since Stardust can stop card destruction, would it destroy Red Dragon Archfiend if it attacked a defense position monster since it's effect destroys all other defense position monsters on opp. field.

Someone smack me please for posting something like this at the wee hours of the morning here in Ohio... time is ... 5:58 am. Don't ask what I'm doing up at this hour...

Asssuming the attacked monster isn't the Stardust Dragon in question, then yes it can negate Red Dragon Archfiend's effect & destroy it.

If Stardust Dragon is not the target of the attack and Red Dragon Archfiend uses his effect, then Stardust can negate the effect.

If Stardust Dragon is the attack target of Red Dragon Archfiend, he is destroyed by battle and can't use his effect.

Okay, thanks. A friend and me were having a dispute over this. Thanks for clearing it up.
