The AI always gets good "Lucky" stuff (except for rangers). They always get the precursor device that makes them more powerful constantly and they always get the precursor device that morphs bad planets into habitable ones. I can almost guarantee no one has ever had the gradual power and the planet one.
I believe the AI is WAY to lucky. Although, it would be to easy to get the gradually powerful one. The Altarians in my last game got 2 "Luky Rangers" in the last few turns.
Luck doesn't help a human player much, so how can you mod it so a person can actually get these?
