Can I flip Royal Oppression to negate Grandmaster's self-Special Summon?!
Grandmaster of the Six Samurai activates its effect to Special Summon itself.
Yes. You can activate Royal Oppression in response to the effect that Special Summons Grandmaster to negate the Summon.
If my opponent has no Six Samurai in the Graveyard and I use Mirror Force, can Grandmaster still Special Summon itself?!
Mirror Force destroys Grandmaster and other Six Samurai.
Yes. Grandmaster can Special Summon itself because the other Six Samurai are in the Graveyard by the time its effect resolves.
