This build is basic for to counter enemy jungle.
Working progress...

Get armor ward 2 pots, go ward RED if they jungler start blue. And the way around.
Start with blue then teleport to enemy's red and take only red(blue). Blue is harder because easy that they stand with it.
Go/recall back and go wolf and clear your own jungle. Get new ward and place at red when 3 min has pass. (repeat)
You can also ward blue.
At red, put the ward in bush at top of red so you see in to the red and lane. (same with blue)
If you have good team maybe you only need to ward red and they ward blue.
