is it possible for one on one fights between a god tier and a Master class and the normal god tier wins? Ex, could a Prince of Rage potentially win against a Lord of Rage by destroying the Rage they command?

A Lord’s Biggest Downfall is their own Hubris. It doesn’t matter how intense their power over Reality may be or how things favor them, sometimes you don’t need to be specially unlucky to be smacked around by a newspaper after all. He didn’t use any Time Powers in that fight either, but Caliborn was given a pretty astonishing beatdown by John during Game Over! So yeah, a normal God Tier should be able to take down a Lord, nevertheless it wouldn’t be an easy fight, specially if the Lord if prepared.
