Forum:Magician's Circle and sakaretsu armour

So my opponent attacks with a spellcaster and I activate sakaretsu armour and then the opponent activates magician's circle. Now does the effect of Askaretsu armour still work and the monster is destroyed if the monster continues the attack after the new monster is on the field, or does the card not work?? 136.160.211.52 20:25, February 4, 2010 (UTC)
