tbh I would reccommend you just try and get it removed. Not to remake it as it would just become tiresome. We will go for the pokemon, people will ask about Arceus feats and try to overanalyze for loopholes, Pragma Spathe will be thrown around as the go to argument, etc. Not worth it tbh. As much as I like this site. Saint Seiya fights are the most annoying fights.
Now listen this is what we do. We take this "loss" a sit there with an honest to goodness smile on our face and let the SS verse gloat while we know the truth of how that fight would go. We know if it wasn't for those restrictions, Arceus would've won. So let's play mindgames :)
I think it boiled down to Causality Manipulation and Pragma Spathe being Infinite Speed (Although even without speed equalization Arceus has the same speed as said attack.) I haven't looked at that thread in awhile.
