Ok I saw a spirit and I saw it came from a sierra and an amber.

This sierra also made:

spirit *2
mistwalker
phantom
nightshade *2

So this one sierra made 6 new top coats.

My question is: is there a point to me studying the lines of this sierra so I can try to make a new black or white coat?

Are there any clues or puzzles to figure out? That's what I'm not sure of. I was going to spend hours studying the linage to try to make a new black and white coat then I thought, how do I know this is even a puzzle or can be repeated?

I will see things, like for example other day I saw a savana and a nile made a new coat, so then I pair up same roos, I did 4 pairs, and not one of them did what I saw happen for other person.

Are their secrets I can figure out looking at other people's success and looking at the meeroos? Is there some "thing" I can do to make a new black and white coat? Some trick or secret to make it happen?
