Alexander slimeyao2 Kasayev is a talented player from Kazakhstan, specializing in the support role in Dota 2.

Alexander's esports journey began in 2024. Initially, he participated in amateur tournaments and played for teams like GOOOOL and rarara, where he gained his first professional experience in Dota.

In January 2025, slimeyao2 signed with the professional team ASAKURA, becoming part of the roster. With his new team, he immediately joined the qualifiers for major international tournaments. One of his notable achievements was reaching the top-8 in the closed qualifiers for DreamLeague Season 25 CQ EEU for Eastern Europe. The team also competed in the closed qualifiers for DreamLeague Season 23 CQ EEU, finishing in 5th-6th place.

On March 7, 2025, as part of ASAKURA, he became the champion of European Pro League Season 24, defeating Mouz 3-1 in the final. However, the team's performance began to decline, and Kasaev moved to L1GA TEAM, with whom he reached the finals of CIS Battle twice, finished in the top 3 at CCT Season 2 Series 6, and placed in the top ranks at EPL series tournaments. But after unsuccessful attempts to qualify for major tournaments in early 2026, he left the team.
