Forum:Six Samurai ruling

"If this card would be destroyed, you can destroy another Six Samurai instead."

An opponent last night used a Six Samurai deck on me. The only question I have is if I use a Lightning Vortex, my opponent can activate her Samurai's effect to protect one of her other face up samurais before my mass destruction takes place? Leaving one of her samurais on the field after the rest being destroyed due to my magic card's effect.

Just got back into Yugioh the past couple of weeks after not playing for about 5 years, so it's a bit overwhelming. The game is totally different, but a lot more strategic it seems so I'm liking it a lot. Surprisingly having a lot of success against my friends who play, but this deck gave me trouble because my opponent kept protecting her valuable samurais
