Save up gold to slow roll for Yasuo and Fiora at level 5.
Slow roll for Fiora and Yasuo 3 star. After hitting them, level up to 6 and 7 slowly to add in more units.
If you are able to hit level 8 on 5-1, do so to complete your comp. Otherwise, hit level 8 when you can to finish the comp.
If you find yourself with a very early Yasuo 3, you can decide to level up instead of looking for Fiora 3. This makes Locket weaker, but you will catch up in levels faster.
