Hi, I'm new to guide and this is my first guide. I main support and I like to play Off Meta stuff and try to do build that work and even could help you climb if you get really good at it.
If you wanna see me play stuff my stream is www.twitch.tv/lordkaminiisama and I mostly speak French tho.

Yes, this is really off meta and your team will mostly be either salty or toxic until you show them that it works.

Glacial augment is really good sinceyou can proc it on your Q. But you could go for a guardian or even aftershock if your really confident on landing the second portion of your W.
Future's market is great since you want your item faster than the ennemy support so you can properly scale. Cosmic insight for the cooldown for more W and R.
Font of life and Revitalize are must so you can make the most out of your healing item and lots of slow + a stun. You can even go for a electrocute or comet.

Pros :
- Good sustain in lane
- Good poke
- Massive healing from your ult in teamfight

Con :
- Not much healing early
- Can get out poke or damage
- Not the best ealry if your adc doesnt have hard CC
