I have finalized my submission. I've done a bunch of rearrangement and expansion of my explanations, including more damage calculations for different EV/nature spreads.
With that being said, I don't understand all of this obsessing over Latios. If you remember back to threats discussion, the biggest target in everyone's mind was SubCM Latias. Thanks to its ability and typing, CAP 5 destroys pretty much all variants of that Pokemon, which is incredibly beneficial to sun teams. I think giving it the ability to beat Latios one hundred percent of the time is just begging for the creation of a broken Pokemon.
I couldn't agree more.
