Forum:Weird Scenario

So I'm playing against my friend's lightsworn deck and heres what happened. It is my turn. I have Hand of the Six Samurai on the field along with Grandmaster of the Six Samurai. He uses Enemy Controller to tribute his monster and takes control of my Grandmaster of the Six Samurai. I have one Grandmaster of the Six Samurai in my hand. Since I do not currently own one on the field, I special summoned it. Then I tributed my Grandmaster of the Six Samurai to destroy the other Grandmaster (that my friend took control of). Since Grandmaster was destroyed by an opponent's card effect (technically my opponent controls it), the effect activates, and I get to return one Six Samurai card from the graveyard to my hand right?

Sorry if its confusing. I tribute my special summoned Grandmaster to destroy my other grandmaster. Thus, since it was destroyed by an opponents card effect, its other effect activates. And since it activates in the graveyard, I get it back right?
