Forum:Shooting SD ATK? (Ceasefire cost?)

My opponent attack with shooting star dragon without activating its effect. he said 'it can attack once since he did'nt activate its effect'. is that even possible?
 * on ceasefire, does it have a requirement? i know this sounds stupid but i'm confused with the fact that Ceasefire's activation has a requirement, which was stated like this "Flip all face-down Defense Position monsters on the field face-up." my opponents justified that since it was separated by a period in the card text it's a cost. please help on this one, because at the back of my head there's a nagging thought that this card wont be limited if that was the case.Assistance on this one is needed badly w/out citing por. --180.194.250.211 (talk) 22:40, June 10, 2011 (UTC)
