cyttorak vs zom vs any 1 vishaanti

two have become a threat to eternity, one has stalemated galactus, which is the most powerful individual mystical entity in marvel outside the abstracts or dr strange with alll his artifacts?

I'll say Zom for now. Cyttorak doesn't have enough on panel feats to tell how powerful he is. Only that the Vishanti fear upsetting him.

Zom stomps, imo.

Zom or Agamotto- http://www.marvel.com/universe/Agamotto

Zom will annihilate them, Eternity himself could not stop him.

zom

zom is far too powerful for these other entities, not even the full octessence or all 3 vishanti can beat him.
