Forum:Attack and chains ruling

A simple question regarding an attack declaration and a chain.

The situation is this: my monster attack and my opponent active sakuretsu armor in response, which i negate using pollinosis. He can't chain anything else so after the chain is over, my monster proceed with the original attack but then he pretend he can activate magic cylinder because this is a separate attack, a separate moment..

I'm almost sure he can't do that and if you cold clarify for me exactly why he can't do that move i'd be very grateful. Thanks 87.13.127.208 (talk) 20:06, December 23, 2010 (UTC)
