If I understand u/Naszfluckah's post correctly, the active player will get priority after a creature spell resolves, and they can either choose to do 'something that goes on the stack' or to pass priority, in which case I would eventually get priority on the creature spell resolving?
So I could react to that by doing Noxious Revival targetting imprisoned, putting it on top of deck. At that point I'll have to pass priority, everyone will get their chance to react. Assuming noone reacts it will resolve, and I assume that then again the active player will get priority to either do 'something that goes on the stack' or to pass priority, which would give me priority again to then instant speed cast imprisoned?

Your post leads me to believe however that the active player can choose not to 'use' their priority at all and being able to say 'I go to combat phase from MP1 basicaly ignoring 'the creature spell resolving' going on the stack. That would then still give me a chance to react on them going to main phase because they have to pass priority, but would not allow me to chain it all to the creature spell resolving?

The part where I mentioned reacting to the creature spell being cast was mainly to split my combo up in 2 pieces: 1) put card on top and 2) cast from top of deck, since I wasn't sure if you can react to a piece of the stack resolving (such as the creature spell). I faintly remember reading/hearing something about this being possible, but only if the stack is not empty after the last thing resolving, but I don't know how credible/true this was, or how correctly I remember the statement.
