Ehhhh
You're saying this (mainly the Othinus part) with in-verse logic or with vs battle logic?
Cause like, Aleister could fight with the MGs and he isn't a tier 1 reality warper or anything like that. Like, Triple Reload can one shot a magic god, Othinus has no resistance to Cold Mistress iirc and apparently these are just their basic spells not their "true forms/final attack" so reality warping aside they may really defeat Gungnir Othinus
We don't see Aradia's final form, but I don't think the Succubus has one or she would have used it before getting lethally injured, no?
What you bring up is kinda what I mean when I say it's under the assumption the opponent wouldn't do anything in defense or retaliation, which makes the entire hype just the biggest technicality ever.
Aradia would, in practice, never had the chance to snowball Triple Reload until it could actually stop Othinus (other than Crowley, whose techniques are more readily available), while the Succubus would definitely have just gotten blinked from existence regardless of Cold Mistress. Portraying it as them being a realistic threat to Othinus is just laughable IMO.
If you go on that level of technicality, Salome could likewise
theoretically built up a chain large enough to defeat Othinus. Irivika could
theoretically take down Othinus just as much as the Succubus with her mind techniques. Yet even the nerfed magic gods were considered basically undefeatable by the standards of such normal magicians.
In that regard the 'defeat the entire magic side' statement kinda just rings empty. Their magic is really not that special by what we already know from magic side magicians (Divine Punishment vs Cold Mistress for example) and, even if we put vsbattles indexing aside, it's more than obvious that they can't match saints in strength, speed and durability.
Btw. what confuses me about the Othinus statement is how it is said that they didn't stop Othinus "in that dark space" because they couldn't rebuild the world... Like, the dark space refers to the alpha world, doesn't it? How would they even have had the opportunity to do that at that point as they shouldn't even exist then...
