Forum:Stumbling question

I have stumbling on my field. My opponent summon monster. His monster changed to defense position. My question is, can he turn the monster to attack position on his next turn even my stumbling still face-up on the field since unlike final attack order, that mention that the monster cannot change battle position. And one more, is the monster that already been summoned before the activation of stumbling, changed to defence position?115.132.47.167 14:25, March 16, 2010 (UTC)
