If Amazo just dupes everyone at fight start, then Amazo.
Solos everyone. Including his own side.
Doctor Destiny is at least sometimes a reality warper the JLA can't punch out due weird metaphysical shenanigans, which probably makes him the only other relevant actor in the face of how fast the Surfer is.
