Ever since i've seen someone play this build, I've been intrigued and have been trying it out. It works wonders with a decent duo partner and can definitely make the game difficult for your opponent

Mm... Just chose some runes that would work with it.
Not sure if it would be better to just get all CD runes or CD/AP runes.

All in Support just for the extra gold (more wards) and extra exp (cuz u get so many assists)

Start with faerie charm 4 wards and 1 health pot.
Finish philo and get boots
Then follow up with Heart of Gold and Kage Pick.

In between, each time you go back buy as many wards as you can or like 2-5 wards. I like to keep 2 slots full of wards when I leave base.

Sometimes it might be good to add an Aegis at the end. because you end up with a surplus of gold.

You can prioritize astral blessing or infuse. Get your starcall last.
I would suggest that you get infuse first and max it first for the harass/silence ability
Otherwise it's pretty straight forward.

Yeah.. Dont farm

I'd go with Clairvoyance and Flash but you can also get Heal.

Go bottom lane with preferably a ranged dps carry. Place ward in River at intersection to watch for ganks from jungle. And ward in lane bush if needed to prevent being harassed.
Try to zone enemy champions using infuse and use your heal on your carry.
It's okay to be a little aggressive in order to let your carry farm

Never stop warding. Ward dragon. Ward their blue. Ward the different intersections.

Once the laning phase ends.
This build focuses on Warding such ganks are improbable. But also when the other team prepares for a gank, your team can see it coming and counter it effectively.

If enemy gets oracles or vision wards just tell your team to target them and use vision wards to kill other vision wards.

Always have 1 Ward in each of the 4 jungle areas. 1 ward in baron and 1 in dragon.

Pros:
Map Hacks
Decent Support
Babysit your carry

Cons:
Squishy
Wards can be killed
Most fights will be 4v5 as you can only heal and silence.
