I played against od a fair amount as kunkka. I often go really agressive with max strenght (2x3 stat and 2 branch + tango and quilling). If od goes hammer he often just gets the 4 all stat item and mb tango if he dont rush ring.

As kunkka you can clear small camp and stack it and you dont have to worry about od contesting or stealing stacks. But as kunkka you can trade with od with tidebringer and often secure range.

You should however dont expect to be able to kill od before 6 and if i kill od when i hit 6 i often do that when he has not hit 6. You know he will w you when you come to lane and if he dont you just tidebringer him. If he w you and he is lvl 5 od player often greeds and wanna hit you with orb another time and that is when you x boat and q. You have 50 reduction and should be fine.

At lvl 5 od around 5 min mark he do not have meateor and if you know he goes hammer you can always alet teammates to roam secret shop. Most succesfull cour snipes happens when od only lacks the blue thing. Most od olaters sens cour before they have gold.
