Ezreal – Guardian
Essentially, the recent overpowering of Dragon Spirit compositions has rendered reroll strategies extremely weak. However, after Riot directly nerfed Dragon Spirit compositions, successfully building them has become much more challenging. As a result, reroll strategies are making a comeback, exemplified by the Ezreal – Guardian team.

The strength of Ezreal – Guardian lies in the fact that you can roll for many 3-star champions without spending too much gold. This is because key champions like Ezreal, Nasus, and Leona all cost 1 gold. With excellent protection from Guardian champions, Ezreal is currently becoming the strongest carry in the mid-game.
Lillia – Dragon
It may sound paradoxical, but the weakening of Dragon Spirit compositions has allowed the Dragon team to make a strong return. Essentially, the Dragon team is still built around a reroll strategy with 2-3 gold carries. Therefore, when late-game strategies weaken, the Dragon team naturally becomes much stronger.

What makes Lillia shine in the current meta is that this champion has received significant buffs from Riot recently. Specifically, Lillia’s damage has been greatly increased at 3-star level, making rerolling this champion an incredibly effective strategy.
Xayah – Syndicate
When Dragon Spirit compositions were strong, it was very difficult to effectively build the Xayah – Syndicate team. This is because the power threshold of Dragon Spirit teams was completely superior to the carries of the Syndicate composition, making it nearly impossible to compete for a top 4 spot. You might even lose an important piece, Shyvana.

After the nerf to Dragon Spirit strategies, Xayah – Syndicate has gradually made its way back into the meta as 4-cost champions have become significantly more valuable. As of now, Xayah – Syndicate is the most stable composition for climbing ranks with a top 4 placement rate of up to 52%.
Conclusion
In summary, with the significant nerf to Dragon Spirit compositions, reroll teams or those using 4-cost carries are making a strong comeback. The compositions mentioned above are the most effective rank climbing strategies following Riot’s update that you should experiment with in the current meta.
