Prioritize Hero units as your primary counter; Gargarensis is a Cyclops/Hero hybrid and takes significantly increased damage from them. Support your Heroes with ranged units while avoiding using standard Myth units, which struggle against his high resistances. Utilize Greek crowd control powers like Frost or Curse to neutralize his escort, as standard Greek civilizations do not have access to the Atlantean Shockwave power during these encounters. Maintain a robust economy to replace the heavy casualties his area-of-effect attacks inflict, and never engage him without a full squad of Heroic reinforcements.
