Fair? FAIR? I do not heed to the concepts of mortals!
Ok then, Runner is awesome.
I mean.
First order of action, create Strange dupes.
Second, Strange protects his team from telepathic assaults with his Eye.
Third, Surfer blitzes Runner, keeping him occupied long enough for Strange to stop time for a moment, then he proceeds to banish Runner.
Strange has a forcefield around himself three times as strong as his normal, which could take a supernova itself, so that rules out any body attacks.
Champ dukes it out with Superman, and easily wins.
Ice man has no mental defenses, he's taken out quickly by either Strange or Warlock.
Cable is massacred by Warlock, litterally massacred. Warlock is his superior in TK and Telepathy, even when Cable is godlike.
That leaves us with Doctor and Fate.
Doctor is an evil man, he's murdered thousands, so Strange can use his penance stare's equal, while Adam attacks his soul.
That's the end of Doc.
Fate is the only one left, he won't know which Strange is the real Strange, the dubes all have power.
Fate gets murdered by Strange and Warlock and Surfer, probably taking Hulk down with him.
