Mordekaiser can maximize his 1v1 combat potential within his ultimate by leveraging the Q skill's AD ratio buff and Zhonya's Hourglass.
Core items include Riftmaker and Rylai's Crystal Scepter; he is particularly strong against multiple enemy tanks.
As an immobile champion, he is vulnerable to CC and mobility; be cautious of counters like Olaf who can nullify his ultimate, and focus on careful positioning.
