To be frank, Raven and co. are probably going to be
2-B/2-A by the next arc

You're still talking about it in the context that Magnus has resisted more powerful Power Nullification. That's his resistance, good resistance yes. But I'm talking about his resistance being bypassed. How can he resist something, when his resistance isn't there anymore and has been completely cut down. Once again, it's like me saying "Well, Raven beat beings and bypassed resistances to those who were created for the sole reason of counterbalancing all her powers via their sheer will to do so". Furthermore, to talk about more of what it did, Grandfather Spider went from
2-C to
High 4-C from what Raven did to him, that's
2 infinites weaker than what he used to be, stripping him from his Shadow Magic to a point Adult
Morganthe could absorb his remaining power (Considering he said he was too scared to fight her in his current state and WoG backing this up by saying Morganthe would have just absorbed whatever power he still had), on top of this, the negation which I talked about earlier. It also seems to me like you're contradicting yourself a little bit, because a following point, you talk about Resistance Negation as if it's literal Resistance Negation, whereas here you're talking about his resistance being the end all of Raven nullifying his powers.
Again, unless it's been directly shown he can pull back to the Warp, especailly when Raven sealed Spider in a way that he couldn't use the means I mentioned before to escape, it's not right to assume he could pull back while being sealed and dropped to
High 4-C. Because that is what she did, when she sealed Spider away, she nullified him down to that power so he would have no chance of escaping the seal, likely because she knew he had the power to do so. And from my previous paragraph "Spider's true divine body (And Raven's for that matter) is a meta"physical" being connected to a realm (Astral plane) that is void of time and exists as a plane that exists between non-existence and existence (Where, even if her form in the real world is destroyed, her astral being will just hang in this place like "okeh"), completely empty with no subjective laws of physics being present"
I don't understand how that is Resistance Negation. That's just him being above their resistances. We can use any other fiction and slap Resistance Negation because "oh, they beat a character with resistance to a specific ability with said ability", unless it's directly stated or shown to be literal Resistance Negation, I don't think it's fair to assume it is such. The Player when he was wall level could do exactly what I quoted. Being immune to specific abilities has been such an irrelevant thing in the game right now, that I could slap Resistance Negation to practically any character if I wanted to using your logic.
That's two different playing fields. That's applying Laws to The Warp itself, I'm talking about it in the context that Raven can manipulate the
laws of Magic to work against him. I'm prettty sure they are going to be in a mutual setting, otherwise things are being swayed way to much in Magnus' favor. And, using what you said, the battle won't have to start in the warp, Raven's go to move is sealing in-verse. Back to Law Manipulation: she can make it so he himself has to follow completely different Laws of Physics than the Warp applies. Her Law Manipulation doesn't have to work on The Warp itself, It's self evident that she can't, but she can impose specific laws on Magnus himself. What happens is, while he is linked to a higher dimensional realm, he will no longer be able to function under it's protection that it's granting him from Raven's wrath.
Omniscience should regardless still allow Raven to see the past and the future (Future in this case is more relevant). That is one purpose of the Eyes of Time. "They were called the Eyes of Time. One showed the past, and the other showed the future". It should still show her futaristic events that will happen throughout the battle, allowing her to preapre accordingly.
