Strategic Tips
Economy
Reach 50 gold, then slow roll at level 7 with only the excess until Kog'Maw and Yasuo are 3-starred.
Itemization
Build Guinsoo's Rageblade, Spear of Shojin, and Guinsoo's Rageblade on Kog'Maw.
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 Bastion Kog'Maw.
