Forum:Kogarashi's Effect

I have a little question: the effect of Kogarashi :"When you Synchro Summon using this card as a Synchro Material Monster, your opponent cannot activate cards or effects." is until the end phase of the turn that was used as a sinchro material monster,or is until the end of the duel?--186.105.194.178 (talk) 02:19, September 10, 2011 (UTC)Manuel
