This guide is written based off PBE, as such, I'll write a more detailed one once set 10 gets live, with level up and roll timings, for instance.

Early game (lvl 5)
With this comp, you'll want to place your units around the Disco Balls, since these will give units starting the round around them stacking Attack Speed as well as healing based on their max HP, every 3 seconds. If you get the augment Double the Funk, the Disco Balls's range will double, allowing you to position your units further from each other, and the bonus will trigger every 2.5 seconds instead.
Reaching 6 Disco isn't that hard, you only need a Headliner with +1 Disco. It's especially strong on the Multi-Talented map, since except for Gragas, all Disco units only have two traits, which will then both count double. On this map, Taric is one of the best Headliners you can have to get started on this comp. We'll see in the detailed guide when to start transitionning into a stronger board.
