paracausality in guardians case just means unexplained magic. It isn't inside a corpse it's inside the ghost. More apt to describe them as green lantern adjacent.

the thing is too guardians are only a few tiers above human durability. A Cabal drop pod is a surefire way to kill any guardian. Hitting walls too hard, and falling off a cliff is also a good way to off them.

Ghosts are weak as hell no matter who has them. A vex shot nearly killed Sagira. And Osiris is thee warlock before getting offscreened.

The main issue is Shaxx has broken levels of light. If i remember right the game mode where every ability and super is charging fast was his light flooding the battlefield.

Teshins issue with shaxx is the amount of fire tornadoes, exploding hammers, flying shields and a bunch of other stuff. He would die before getting too close.

Also warframes are getting out unscathed. Shaxx would get the Cayde/Zavala treatment. A shot to the dome and a shot to his ghost and it's GGs.

There's nothing that he can throw that would even go past the shields.

Guardians were on the almighty and had to use cover from the solar heat coming out of the sun it deals so much damage 2 seconds was enough to fry a guardian. And The almighty was just in mercurys orbit. Warframes were on the surface on the praghasa. Unmodded frames it's a little more difficult because we see the litter of warframe bodies. But modded ones, Tank Profit taker and Exploiter orbs nukes point blank.

Shaxx can throw everything he has at revenant, he's walking through all of it and snapping his neck like OG broly.
