RE:You can only control 1 "Grandmaster of the Six Samurai" monster. While you control a face-up "Six Samurai" monster, you can Special Summon this card from your hand. When this card is destroyed by your opponent's card effect, add 1 "Six Samurai" monster from your Graveyard to your hand
Can I summon Grandmaster from a monster such as Spirit of the Six Samurai?
I mean Six Samurai is in its name.
I have been getting a lot of mixed answers and I cant seem to find an official ruling
