Head-to-head Dota 2 7.41e win rate from ranked matches.
In Dota 2 7.41e, Undying wins the Mars vs Undying matchup: Undying beats Mars in 60.02% of 878 ranked matches.
Picking Mars when Undying is in the pool is a big risk, and this matchup is the reason why. The entire point of Arena of Blood is to trap key enemies for your team to burst down. Undying completely dismantles that with a single button: Tombstone. As soon as Mars commits his ultimate, Undying can drop the Tombstone right in the middle of it. The Arena immediately fills with zombies that block spears, absorb God's Rebuke damage, and generally cause chaos. Mars can't pin anyone to the wall and his team gets swarmed.
This dynamic basically shuts down Mars's primary impact from the mid-game onward. Any time he tries to make a play with his ultimate, Undying has the perfect answer ready. The fight Mars wants—a controlled execution—becomes a messy, drawn-out brawl that heavily favors Undying's team. For Mars to have a chance, his team needs to either focus and destroy the Tombstone instantly or somehow kill Undying before the Arena goes down. Meanwhile, Undying simply has to wait for Mars to act and then press his button.
