Forum:Yomi Ship vs Ninja Grandmaster Sasuke

Does Ninja Grandmaster Sasuke's effect negate the effect of Yomi Ship? My friends say that only Yomi Ship is destroyed, however I have to disagree simple by reading Ninja Grandmaster Sasuke's effect, it says when he attacks, therefore I feel that Ninja Grandmaster Sasuke does indeed battle with Yomi Ship, there Ninja Grandmaster Sasuke is destroyed...or am I wrong? Please help end this debate among me and my friends.
