Batrider + Puck

Why this works

Thinking this is a free kill setup is a common mistake. In practice, Batrider and Puck often get in each other's way because they're trying to do the same job. Both heroes want to initiate fights, and both deal primarily magic damage, which makes it simple for opponents to build items like a Pipe of Insight that counter the whole plan. Their control can also be awkward to combine. Batrider wants to drag a single enemy far out of position with Flaming Lasso, while Puck prefers to lock down an area with Dream Coil. The result is two heroes competing for the same role, often leaving their team without the physical damage needed to kill tanky targets or take towers.
