I saw that in overused pokemon there are Gliscor, Larvesta and Scizor, which first evolutions are in same egg group of Paras. Paras is a good pokemon to farm because of the mushrooms he hold. Can i do something with non 31 iv paras i catch? Also, how can i start from paras to finish into scyter? I need a 4x31 female scyter and a 4x31 paras do to a 5x31 scyter?

I searched for a while into the forum but i couldnt cleary understand. I found that egg doesnt hatch by steps but by a timer. How that is influenced by flame body?
