Source: Official balance notes

For your army: Stone Slammer is not in the 9 Jul 2026 change list, so guides written since the TH18 release still apply to its stats.

The 9 Jul 2026 update changed Dragon Duke, Dragon Rider, Logger, Electro Dragon, Meteor Golem and Druid. Supercell's stated goal was to reduce Dragon-heavy TH18 armies: Dragon armies were roughly 20% of TH18-vs-TH18 war attacks, and Dragon plus Thrower-Healer armies roughly 40%.
