How does the scarab god's second ability interact with creatures like lord of extinction (and friends)?
Not particularly well.
The Scarab God’s ability overrides all information about the copy’s creature types, color, and power/toughness. This means that no information related to those characteristics are copied, including any characteristic-defining abilities.
A token copy of Lord of Extinction created by the Scarab God won’t have the “Lord of Extinction’s power and toughness are each equal to...” ability, meaning that it won’t have any abilities at all. (And yes, it would be now buffed by Muraganda Petroglyphs.)
