Well the limitations clearly stated that users of Singularity and Uniqueness are immune, and omnipotent beings are both Unique and Singularity so that a big draw back for this power.

Mimic/copy:

Character: the power of Pre-Retcon Beyonder or Thanos with HOTU ( Heart of the Universe) if I can but if I'm not capable I will copy Franklin Richards' reality warping power "Mentifery"

Artifact : Heart of the Universe if can't then the powers of all six Infinity Stones(Marvel Comics)
