How Mars and Naga Siren perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Mars and Naga Siren win 43.44% of ranked matches when playing on the same team, over 122 matches.
Picking Mars and Naga Siren together creates a fundamental conflict in your teamfight plan. Naga Siren uses Song of the Siren to pause the fight, either to set up or to disengage. During that time, however, all units become invulnerable. This completely negates the damage from a well-placed Arena of Blood by Mars. You're forced to use these two massive ultimates sequentially instead of together, which is often too slow and clunky. It creates a window where enemies can either escape the Arena after the Song ends or simply re-engage once one of the spells has been wasted, effectively neutralizing your biggest teamfight tools.
How this pairing performs across skill brackets — the duo's team win rate in recent ranked matches, split by average match rank. Ranks with too few recent matches are omitted. These rows use the last 30 days of quality-filtered ranked matches, all patches in that span combined — a wider window than the patch-scoped count above, so the per-rank match totals can exceed it.
