Forum:Number 39 Utopia Question

I have one material left on number 39: utopia, my opponent attack number 39 utopia I negated the attack by detaching my last matterial, to negate it's attack, he started arguing with me that number 39 utopia is destroy because he was targeted by an attack while he has no material, but when he attack it still had one matterial. Is number 39 Utopia destroyed immediately after detaching the last material, to negate the attack?96.44.92.186 (talk) 17:31, May 22, 2013 (UTC)
