Night Stalker + Tinker

Why this works

Pairing these two seems like a good idea on paper. You expect Night Stalker to create chaos, locking down a target with Crippling Fear for an easy Tinker kill. The reality is that these heroes play completely different games. Night Stalker is an aggressive brawler who wants his team grouped up to exploit the vision advantage he creates at night. Tinker, on the other hand, is a solo operator. He needs space to split-push and farm for his core items, almost always positioning on the opposite side of the map from any action. He provides damage from afar, not by joining a gank.

This often leaves the team feeling split. While Night Stalker is forcing fights during the first few nights, Tinker is busy farming lanes and pressuring towers elsewhere. This can work if the enemy team is disorganized and can't respond to both threats. More often, a coordinated opponent will either collapse on the isolated Night Stalker or punish the rest of his team for playing a man down. Because Tinker isn't present to add his burst or control, Night Stalker's aggression can easily backfire, leaving both heroes unable to execute their game plans effectively.
