The Rise of Heartsteel
In patch 13.24, the Heartsteel trait received a substantial buff from Riot Games, with champions like Ezreal, K’Sante seeing increased damage. This change ensures that the Heartsteel trait is no longer too weak in the early game and can “explode” multiple times during battles in Teamfight Tactics.

With the abundant resources from the Heartsteel effect, players can aim for level 9 and utilize high-value 5-cost champions. Illaoi and Ziggs are examples of such champions as they provide substantial tankiness and damage output for the composition.
Building the Heartsteel – Radiant Composition
If players can’t find Heartsteel champions early on, they should start with any Star Guardian Corki and the Hardcore Fans trait. Corki is an excellent holder of items for Ezreal, making it a strong choice in the early game. Additionally, providing free items to Star Guardian champions from the Hardcore Fans trait will help players maintain good health.

In the mid-game stage, players should transition to using the 4 Big Ear Warriors threshold to ensure damage output. In the frontline, Ranger champions prove to be a solid choice due to their high armor/magic resistance stats. If players can activate the Heartsteel trait with Sett, K’Sante, Ezreal, they will have plenty of resources in the mid-game.

After reaching level 8, players should use gold to search for Star Guardian Ezreal and upgrade the composition to 2 stars. Following that, it’s all about holding resources to reach level 9 with high-value 5-cost champions like Illaoi, Ziggs.

In terms of items, Ezreal requires Infinity Edge and Red Buff to optimize damage output. The final item for Ezreal should be Giant Slayer or Blue Bow. With the Technology Core options, upgrades that grant experience are particularly suitable for this composition. They will help players shorten the leveling process to 9 and quickly acquire 5-cost champions.
Conclusion
With many reroll strategies heavily nerfed in patch 13.24, the Heartsteel – Radiant composition has risen strongly due to its dominant late-game power. This is expected to be an extremely effective climbing strategy that players should take advantage of right now.
