Can Malik mask his evil aura from total strangers? That be only reason as to why she'd attack someone she'd never met before.
I can't think why she's be able to detect him controlling someone's mind. Nobody else can in the Yu Gi Oh cannon unless they hold a Millennium item, and even then, they're not detecting him, they're detecting the Millennium item he is using.
Given that both Atem (who has almost as much bullshit magic and Sailor Moon) and Ishisu (who has psychic powers, can see the future and is Marik's own sister) were unable to detect him is someone's head, I don't think Sailor Moon could.
Transporting the soul is interesting, but even if she were to lose the shadow game, she wouldn't lose her soul. She would just be reincarnated again through the Galaxy Cauldron because her soul is connected to it.
If you're trying to suggest that Malik could incapaciate Sailor Moon by stealing her soul, its not going to work.
For a start; I'm not sure how forcing a person to be reincarnated doesn't count as incapacitating them.
Secondly: 4Kids to the rescue. He soul doesn't get destroyed and as such cannot actually be reincarnated. It is trapped in a prison in the shadow realm awaiting rescue al la Mie Valantine. Sailor Moon would not be dead, but she would definitely be incapacitated.
On an unrelated note; you already accepted my logic in the previous round as to why Marik defeats Sailor Moon, and I'm not understanding what has changed with her new form. She's faster and more physically powerful, but she was both of those things already. Until she develops a form that isn't shit at card games it won't do her any good.
Not sure why you think Sailor Moon is unintelligent; passionate and headstrong, sure, but unintelligent? No.
Because she is an underachieving sixteen year old highschool student despite having almost unlimited magical powers and accessories? She also doesn't know how to play Duel Monsters, so even if she were Stephen Hawking in this context, it wouldn't do her much good.
