C´mon guys it is not obvious
We know now that Magneto had defeated Thor and had battle the Sorcerer Supreme Dr Strange and go out well of the encounter, the power of Strange proves worthy against Mags but just because wield magic doesnt mean you can play cheap against him, Magneto is also father of Scarlet Witch, which is about the strongest magic holders even at some point could surpass that of the sorcerer Supreme, Mags have deal with his daughter too.
Násrist a powerful demon of a similar origin as Mephisto strong in the magic arts dont hesitate to make war to heroes and villains alike that get in its way; However the Demon approach Magneto with the purpose of make an alliance; what this tell to you what more proof could you want.
Magneto posses arguably among the top 3 defenses in Marvel. The Great Magnetic Force Field which can withstand a direct hit from Galactus and Phoenix and obviously he have bastlya arsenal not just his magnetic force but his sort of pink-purple plasma photonic energy that emanates from all his body but mainly his hands and eyes, the domain in the elctromagnetic spectrum, capability to make EMP to mess with the earth devices, create earthquakes global scale ergo ring volcanos, lift objects as big as asteroids, feed or charge from the electromagnetic particles of the environment to enchance his strenght speed and stamina, unlimited reaction time due to fast synapsis almost every being that functions or operates with bioelectric connections or electricity is scwd cause he can affect and manipulate, has played god by creating life mutant has high level intelligence in technology, genetics physics, strategist, strong will to disrupt mind manipulation for the strongest telephat Xavier, Frost , Jean grey.
Dr Doom in the secret wars, when he saw the t Beyonder put Magneto in the side of the good guys, what did Doom do?
In his own way ask Magneto to reconsider in which side he was fighting; Doom see Him as a threat even he had Kang the conqueror Ultron and other on his side.
Facts, actions tell that Magneto could be considerated as a Omega Level so then he could have been then a Cosmic level long time ago. If the writers want to take the next logical oficial step (because at the eyes of many he already is) let him evolve and surpass his human bonds because of his inner possibility due the embodiment of the Universal Force. Although this might end in a consideration ina god-like being making him less popular to the to people because of this.
Magneto is among the five not considering Cosmic Entities biggest threats of Marvel along with Dr Doom.
Lucky will be lucky to go out well of the encounter and his life spared cause Magneto hate manipulators and cheaters
