Anos made the "anything in existence" comment which included knowledge of Venuzdonoa's magic which is something that contains deeper laws and concepts of the silver sea. It is clearly not limited to "inside the world" as the knowledge used to make Venuzdonoa comes from things that are "outside existence" as you call it.
Unfortunately, this has nothing to do with the point i was making. This debunk was referencing your standpoint that "it is headcanon to assume that Order besides 'power flows from shallow to deep' exists in the silver sea". I proceeded to prove that the same Order in the bubbles is the same Order in the Sea as a Creator god cannot create Order that deviates from the one that gave birth to it which is the Order of the silver sea.
Your standpoint in regards to this is "all of existence" only refers to the world inside the bubble, this would naturally include Order. The Order in the bubble is the same Order of the silver sea albeit with a weaker influence but Venuzdonoa does not care about a power difference. It destroys the "Reason/Logic" behind anything to destroy what is classified as "Anos enemy". This is evident in the fact that despite the huge difference in magic power between Kostoria and Sasha, Sasha's Venuzdonoa still operated on the same level as kostoria's and despite kostoria's merely being a copy, it was on the same level as the real thing. "The logic of a power difference, being inferior cause it's a copy" is meaningless before the ability to destroy logic
It matters because the very fundamental in Venuzdonoa's magic formula is something deeper than the scope of the world to begin with. "As far as he knew" is irrelevant as Venuzdonoa is already an existence beyond what he knew and he makes the statement it destroys anything
regardless of its logic, how sturdy, eternal or infinite it is. This is even more evident where it destroyed graham who like anos is outside the order, reason & logic of the silver sea entirely. Even the logic of "I am beyond/outside/unbound from logic thus i cannot be affected by affecting logic" is useless before Venuzdonoa. Even the very logic behind this CRT is useless before it.
This isn't to say Venuzdonoa is omnipotent as most people including you have tried to use to debunk it as even factoring in Venuzdonoa Anos has said
he isn't omnipotent
but the one thing he remains unrivaled in, is absolute is his power to destroy.
The retrograde formula is a magic to
reverse the flow of Order in the
entire Silver Sea to temporarily bring Concepts and Laws that don't exist in shallow layers from deeper layers which allows deep magic to function in places where the laws and concepts for it don't exist.
Inferior characters are already capable of affecting the sea not to talk of Venuzdonoa that's superior to them and can
destroy rather than
merely affect
