In your original post, you said:
And I already wrote up my approach, giving a 20th-level mage as much time to research your sorcerer as your sorcerer took to establish his castle (odd choice for a "master of disguise") and his army (likewise). All the wizard needs to do is find out the sorcerer's name, or an epithet he's chosen, or what his followers call him. At that point: one simulacrum casts wish to turn off the sorcerer's magic; the second simulacrum casts wish to bring only the sorcerer and any extant clones to the wizard; the wizard makes the sorcerer dead.
It does not matter how many minions or simulacra the sorcerer has. This approach kills him dead. Works on any spellcasting class--any class, really, including wizards (though in a more in-game situation, you'd need to word the wish so the antimagic field included the victim's equipment). It's not a fun way to play the game, so I don't have people doing it in my games (because I don't have NPCs using simulacrum and the PCs haven't taken it).
Wizards really are scarier than any other class if played with the right motivation. Lots of power and the intelligence to use it.
I don't see anything in there about no simulacra, but that's fine.One vs One
No multiclassing
No magical items
No infinite loops
No coffeelocking
