>>38201929Next up are the Mortality Trio, Xerneas straight off the bat would ruin Slifer but get destroyed by Ra, and since Obelisk's Fire-Type would resist the Fairy-Type Xerneas is a poor match overall. Yveltal does fair a bit better doing poorly against Slifer but being able to body Obelisk and would go toe-to-toe with Ra thanks to Steel losing its Dark-Type resistance last gen. Overall it's a neutral outcome for Yveltal. Lastly is Zygarde who would likely dominate Slifer thanks to the Ground-Type advantage giving it a clear edge, this would also continue to Obelisk as well with only Ra having the distinct advantage against it thanks to the Steel resistance to Dragon-Type and Flying's immunity to Ground-Type.
Overall I feel like Kalos could also go either way although if Ra can take out Zygarde then it's all over for the Mortality Trio.
Lastly we have the Light Trio. The Psychic-Type means all three are fucked to some degree by Obelisk which I'd probably argue means an instant win for the Egyptian Gods but we'll see how Slifer and Ra fair, Slifer would do poorly against Solgaleo and would be neutral for Lunala and Necrozma so it's slightly weak in this situation, meanwhile Ra actually has a fairly decent run, thanks to it completely locking out Solgaleo and Necrozma on the resistance side and going neutral against Lunala.
Overall it's a pretty clear victory for the Egyptian Gods against the Light Trio.
So overall I'd say that the Weather Trio could beat them, the Dragon and Mortality Trio could go either way and the Creation and Light Trio would likely lose.
This isn't including Giratina, Kyurem, Zygarde or Necrozma's alternate forms which for the latter three would help them in likely sealing a victory.
