Axe + Meepo

Why this works

Landing a multi-hero Berserker's Call sets up an ideal kill zone for Meepo. With enemies locked in place and forced to attack Axe, Meepo can bring all his clones to the fight with Poof for a massive burst of magical damage. The taunt guarantees the targets cannot escape the damage or turn on Meepo's main hero. As the enemies are held, Axe gets multiple chances to spin with Counter Helix while Meepo's clones surround them for the follow-up physical attacks. This combination of lockdown and burst can delete a key target before the call even ends.

The whole game plan becomes very direct once Axe has a Blink Dagger. He provides the strong initiation and control that Meepo's kit lacks, allowing the pair to hunt for pickoffs anywhere on the map. Meepo's high damage output confirms kills during Axe's lockdown, accelerating his farm and letting the team secure objectives. The enemy is forced to play spread out and reactively, as a single successful Blink-Call can turn into a lost teamfight and a destroyed tower. Axe creates the opening, and Meepo has the numbers to exploit it.
