It's good to hear updates from scorpion. My players lately are nailing everyting even on these statblocks.
My group has just obtained Father's blood and is ready to go to the prison. They use Mythic Heroism extensively so it would be nice to use it against them.
Let me ask you two things:
1. Svendack is strong enough as written and you didnt change her?
2. Regarding Baphomet's Summon Minotaurs. He can summon 3 times per day 8 half-fiend minotaurs. Simple minotaurs with the half-fiend template???
And once per day 4 mythic minotaurs or one labyrinth minotaurs. I guess the mythic minotaurs are like the miners on midnight isles and the labyrinth minotaur is the Ivory minotaur??
