Anti-Mage + Slark

Why this works

Spreading the map with two slippery cores can be a double-edged sword. Both Anti-Mage and Slark need a lot of farm, which can starve the rest of the team. The upside is that both are incredibly difficult to lock down. Anti-Mage's Blink and Slark's Shadow Dance allow them to farm dangerous parts of the map that other heroes can't. This creates a difficult choice for the enemy: commit multiple heroes to hunt one of them, leaving the other free to push a lane and take over the opposite side of the map, or stay grouped and cede huge amounts of farm.

This lineup often plays from behind in the mid-game, looking to trade objectives rather than take full teamfights. The enemy will typically group as five to exploit your team's split-pushing nature. Your goal is to survive this phase and get core items on both heroes. If Anti-Mage and Slark can successfully drag the game out, the enemy has to contend with two independent, high-damage threats who can strike from anywhere. A successful gank from one can create the opening the other needs to secure an objective and accelerate toward a win.
