Batrider + Pudge

Why this works

Drafting both Pudge and Batrider for the same team commits your lineup heavily to single-target initiation. Both heroes want to accomplish the same goal: isolate and kill one key enemy. Batrider gets in close to land a Flaming Lasso and drag a target back, while Pudge looks for a long-range Meat Hook to do something very similar. The issue is that their skills overlap more than they combine. Chaining a Hook into a Lasso is usually overkill for a single kill, and it means two of your team's most important spells are spent on one hero, leaving you vulnerable to a counter-attack.

This one-dimensional strategy can be figured out and played around. Opponents will group up earlier than usual, making it difficult for either Pudge or Batrider to find the solo target they need. Good positioning and support items like Force Staff or a Lotus Orb can completely negate your team's main plan. When the initiation fails, your side is often left without a strong teamfight presence to fall back on. The lack of diverse threats means that if the enemy survives the initial pickoff attempt, they can often turn the fight around and take control of the map.
