- Corner Lulu on the back line and put Rhaast in front of it.

Reach 50 gold, then slow roll at level 6 with only the excess until Milio, Jax, and Lulu are 3-starred.
Itemization
Build Crownguard, Gargoyle Stoneplate, and Gargoyle Stoneplate on Jax.
When to pivot
Scout at 2-1 and 3-2: if two or more players hold your core units, or you haven't found any by 3-2, move into one of the comps on the Similar Comps tab instead of forcing Replicator Jax.
