Forum:The Six Samurai - Yaichi's effect

So me and my little brother come across this situation a lot. I have my field of samurais and hes running an Alien deck. If I activate Yaichi's effect to destroy a face down, and he chains it [continuous trap] with a card such as Brainwashing Beam, does that mean Yaichi's effect is null? We've been playing as if it had lost a target, but a confirmation would be appreciated. Thanks in advance JTNVinh 05:52, 19 May 2008 (UTC)
