Head-to-head Dota 2 7.41e win rate from ranked matches.
In Dota 2 7.41e, Marci wins the Marci vs Io matchup: Marci beats Io in 51.12% of 3,214 ranked matches.
Trying to blow up an isolated core is Marci's whole game, but Io is built to counter exactly that. Overcharge provides a huge amount of survivability against Marci's physical burst from Unleash, and a well-timed Relocate can completely invalidate a gank attempt. The bonus movement speed from Tether also makes it harder for Marci to stick to her target. However, Marci is mobile enough to get on top of Io directly. If she can burst the support first, the save never comes. She can also use Dispose to throw Io away from his partner, breaking the tether. This makes the fight a toss-up based on positioning and target priority.
