I´ve my 4x Aetherworks marvel foil and now in Standard I can´t play it. Well, I want make it in Modern.
I need help and I want make it better
You'd probably do better with the Standard deck than this.
Ancient Stirrings can help find the Marvel (or lands to cast it).
The problem with a deck like is that it does nothong without Marvel and there is no reliable tutor for it in R/G so you have to splash Blue (for Fabricate) which is othewise unecessary.
And it is still pretty bad (a worse version of a Breach deck).

Some more decent ramp options that sac' themselves:
Sakura-Tribe Elder (or Dawntreader Elk), Generator Servant (or Wild Cantor).
