STAGE 5+ - FINAL BOARD!
The central strategy of this composition typically centers around Heartsteel. You can opt to prioritize Heartsteel from the outset or focus on building the strongest board until you're able to activate the trait. It's essential to maintain a robust economy while prioritizing the accumulation of Heartsteel units, even if it means sacrificing some of your HP.
Following this approach, you should aim to reach Level 7 by Stage 3-5 and Level 8 by 4-2, where you'll roll for a Tier 4 Headliner. Typically, Ezreal will serve as your primary AD Carry, while Zed can make use of any leftover AD items. Once your core setup is solidified, consider pushing towards Level 9 and incorporating additional Legendaries such as Illaoi, Lucian, or Jhin into your composition.
Adaptation is key as the game progresses, with your composition evolving based on the Headliner units available. This flexibility might lead you to end up with compositions featuring 4 Big Shot, 4 Crowd Diver, or 4 Bruiser units in the late game.
