Start your game with your Trainer duo Heimerdinger and Tristana in the back to start feeding Nomsy from the earliest stage possible. For your frontline you can run a Bruiser duo like Tahm Kench and Skarner. Use Tristana to hold items for Varus.
Continue building your team and start adding in Astral 3 by running your 2 most important units - Varus and Illaoi. Get rid of Tristana when you find a copy of Lulu and transition the items on to your main carry. A copy of Sylas will also let you activate Mage.
