Timbersaw + Sniper

Why this works

A core problem for this pairing is how much farm and experience both heroes need from the map. Timbersaw requires early items to survive his aggressive dives, and Sniper needs his own expensive items to deal damage from the backline. Their kits offer no help to each other in securing this farm. Timbersaw's entire game plan revolves around using Timber Chain to get into the middle of the fight and cause chaos, but this mobility does nothing to protect a static hero like Sniper. When Timbersaw dives, he abandons his backline, leaving Sniper completely exposed to enemy counter-initiation.

This forces the team to choose a game plan that leaves one hero feeling useless. If you play a slow, front-to-back style to protect Sniper and siege towers, Timbersaw can't find good angles to get into the fight and deal his damage. If the team instead enables Timbersaw's chaotic, dive-heavy aggression, Sniper is frequently left behind and picked off by the first enemy hero that turns on him. Smart opponents will wait for Timbersaw to commit and then immediately collapse on the isolated Sniper, winning the fight before it can truly begin.
