NS is exactly like sarah's advanced but instead of solving with only hedges and sledges you do a move optimal algorithm to solve the puzzle.
Thanks for the compliment! I don't know which cube you are talking about :/ I think if you are talking about the sticker mod on the transparent puzzle that has the cacti looking shape, I didn't do that. If you are talking about the green sticker mod black puzzle I didn't do that either. There are some mods in there though
