These team compositions have been significantly empowered by Riot Games in the latest version of Clash Arena.
Heartsteel
Introduced as the new 'jackpot' race in Clash Arena season 10, but the circumstances of Heartsteel appeared quite dire in the previous version. The main reason comes from the prevalence of reroll compositions, utilizing many 3-star champions that completely dominated the 13.23 meta and accelerated the pace of the game significantly. As a result, the Heartsteel composition often found itself eliminated early without being able to reach its full potential.

However, in patch 13.24, this race has been comprehensively buffed by Riot. Firstly, a series of champions such as K’Sante, Yone, Ezreal, Kayn have had their damage increased, aiding players in sustaining better. Additionally, a number of reroll compositions have been heavily nerfed, making it easier for the Heartsteel race to survive until rewards are obtained.
8-bit
Despite having an intriguing stacking damage capability, the 8-bit race itself seems relatively weak. As a result, this composition couldn't compete with strong reroll strategies in the previous version. Instead, 8-bit mostly activates at the 2-unit mark as an additional enhancement for the team composition.

In patch 13.24, this could change as the stacking SMCK stats for this race have been increased from 3.5/6/10% to 4.5/7.5/12%. Additionally, the output damage from Caitlyn 's abilities has been significantly boosted, providing the 8-bit race with a truly potent core. These changes promise to secure a stronger position for the 8-bit composition in the current 13.24 version.
Divine Deer
For a composition with many frontline powerhouses like Divine Deer , strong crowd control units are considered as 'nemesis'. Unfortunately, season 10 possesses too many units of this type such as Amumu, Ekko, Thresh ... Consequently, the Divine Deer composition, despite its great potential, is entirely disregarded by players.

In patch 13.24, Riot even buffs 4 champions of this race including Yasuo, Yone, Viego , and Kayn. The goal is to increase the damage output of the Divine Deer composition and make them more useful in the next version. This is a necessary move to balance Clash Arena as long-range powerhouses have proven to be too strong in the previous version.
Conclusion
With significant power buffs from Riot , team compositions including Heartsteel, 8-bit , and Divine Deer are poised to rise strongly in the current 13.24 patch. Players should capitalize on these compositions to climb the ranks more effectively in the new version.
