@Thomas33,
First, you have to define what you mean by 'master'?
But in general, I would say someone with what we might call God-like powers would probably have to have power over creation - meaning they bucked the Uncertainty principle and so can create anything out of anything. And maybe, depending on what the solving of the UP involves, control over gravity*.
*It might be that solving the UP involves the defacto control of gravity..
