In the group stage of IEM Melbourne 2025, we are set to witness a clash between The Mongolz and Complexity. Both teams have shown different performance dynamics lately: The Mongolz are striving for stability, while Complexity has gained good momentum.

Current Team Form

The Mongolz

The Mongolz are showing an unstable form leading up to IEM Melbourne 2025. The team's average rating at S-tier events over the past month stands at 6.0. They participated in two major tournaments — BLAST Open Spring 2025 and PGL Bucharest 2025. At the first event, The Mongolz reached the lower bracket final, finishing in 7th-8th place, while at PGL Bucharest, they couldn't make it out of the group, concluding with a 2-3 record.

Out of their last five matches, The Mongolz secured only two victories — against FURIA and Liquid. The other three games ended in losses to Falcons, Apogee, and 3DMAX.

Complexity

Complexity appears to be a more cohesive and confident team. Their average rating at S-tier tournaments over the past month is 6.1, slightly higher than The Mongolz. The team performed particularly well at PGL Bucharest 2025, confidently advancing through the group stage (3-1), reaching the semifinals, and ultimately finishing fourth. Additionally, Complexity won the BLAST.tv Austin Major 2025: North American Regional Qualifier, securing a spot in the upcoming major.

It's also worth noting their victory at the YaLLa Compass Qatar 2025: Closed Qualifier, although the team opted out of the main tournament. Out of their last five matches, Complexity won three — against BLUEJAYS, Getting Info, and Aurora. Two losses came against top teams FaZe and G2.

Team Map Pool

Based on statistics and team preferences, in the first ban stage, The Mongolz will likely ban Train — their frequent permanent ban and a strong suit for Complexity. The American team, in turn, will almost certainly remove Mirage, which consistently ranks among The Mongolz's strongest maps. In the pick stage, The Mongolz will likely opt for Anubis, where they have an impressive 75% win rate. Complexity, in response, will probably go for Nuke, as it's one of their strongest maps (80% win rate), especially if Anubis is taken by the opponent.

In the second ban stage, The Mongolz will try to remove Nuke if it's not picked by Complexity to avoid risking against such a confident opponent. Complexity, on the other hand, might close Dust II or Ancient, aiming to reduce risks with the remaining maps. Consequently, Ancient seems the most likely decider — a map that is in both teams' active pool and doesn't show significant win rate drops. A fierce battle is expected on this map, where much will depend on the current form of the players and the quality of execution in crucial rounds.

Head-to-Head Encounters

In the past six months, the teams have faced each other once — about two months ago. In that match, The Mongolz emerged victorious, defeating Complexity 2-0. Although that result might boost The Mongolz's confidence, it's important to note that since then, Complexity has shown growth and improved form.

Match Prediction

The match between The Mongolz and Complexity promises to be intense. On one hand, there's the instability of The Mongolz, but with good individual potential and a history of winning the last head-to-head encounter. On the other, Complexity, who have confidently navigated several tournaments, consistently perform at major events, and have a slightly higher average rating.

The map pool is unlikely to give a distinct advantage to either side; however, The Mongolz's priority ban of Train might weaken Complexity's pick. At the same time, Complexity's ban of Mirage will neutralize one of The Mongolz's main weapons.

Prediction: Complexity wins 2:1

IEM Melbourne 2025 takes place from April 21 to 27. The entire tournament is held in Melbourne, Australia at the Rod Laver Arena. Participants compete for a prize pool of $300,000. You can follow the results and progress of the tournament through this link.
