Brother, what are you even talking about? We see, like, two times Oden using his sword? and suddenly him not having green flames confirms?
Why did Zoro not have flames before enma? He didn't have COA? He got in wano?
You're still yapping about the same sh*t. The manga literally shows you that multiple people had that trail, including Zoro, and many people didn't. Sometimes it was suddenly different for only Zoro.
Why was Luffy Trail gone in some attacks? h
e suddenly stopped using acoc? get your head from your agenda.
