Lone Druid + Witch Doctor

Why this works

Setting up for Death Ward usually relies on some reliable lockdown, and Lone Druid's Spirit Bear can provide it. An Entangling Claws proc is often all Witch Doctor needs to land a full Maledict and channel his ultimate on a key target. The two units from Lone Druid also give Paralyzing Cask more things to bounce between, sometimes extending the disable just enough to secure the kill. This gives the pair a decent way to score pickoffs, especially once the bear is durable enough to stay in the fight and consistently apply pressure on the front line.

In practice, this duo looks to turn a successful gank into an objective. Lone Druid sends the bear to find a root, and Witch Doctor follows up with his spells to delete an enemy, which opens up the map for a tower push. The main weakness is that the combination is focused on a single target. Enemies will prioritize Black King Bar to negate the Maledict and Cask, or Ghost Scepters to survive the Death Ward itself. If the initial target gets away or the enemy team simply groups up, the setup loses much of its threat, which keeps this pairing useful but not overwhelming.
