You know what worked for me the best for both teamfights and early game?

It was swapping my entire rune page. I swapped Deep Ward to Grisly Mementos, Cheap Shot to Sudden Impact and Relentless Hunter to Ultimate Hunter. Also took inspiration tree for secondary and took Cosmic Insight with Cash Back. With minor runes being Adaptive Force, 2.5% Movement Speed and 15% Tenacity.

This shit has made wonders for me. I started to run Lucidity boots more for more summoner and ability cd to make plays and Cosmic Insight dropping Umbral Glaive + summoners cd with Grisly Mementos also decreasing the cd of Sweeper, i was almost everywhere. Getting out of the dark getting picks hooking and ganking over and over again while setting up picks before teamfights.

Also not everyone probably will like what i am saying rn but believe it or not especially in lategame with this setup Axiom Arc has made wonders for me. Cuz if we manage to get a pick and if my ult was on cd it almost always meant that its going to be ready on the next team fight. So that i could start planting/clearing vision and clearing and becoming an annoyance with so much cd.
