+1 tier in strength with Artifact. VI 3 is stronger than Krug 3. Item priority: Master Yi/Rengar > Tank > Nidalee. Only take Phoenix Primal buff if ahead. Otherwise, Execute / Healing Primal. Rengar and Yi have the exact same BIS. Yi is stronger but itemize whoever is upgraded first.

Stage 2: Ideally play around a Rengar opener that can win streak. Blossom is very powerful to get early econ or item wisps.

Stage 3: Add more Adaptors and frontline as you go. Finish Yi/Rengar items by end of stage. You can even play 5 Blossom for maximum Wisp greed if you highroll the 4 costs.

Stage 4: Level to 7 and roll for Master Yi 2, Rengar 2, and a Juggernaut Tank. Econ up and slow roll for 3*. Add Kog or a flex unit in at 8.
