Wraith King + Treant Protector

Why this works

Trying to bring down a farmed Wraith King is already a huge task, and Treant Protector makes it even more difficult. The constant global presence of Living Armor means Wraith King can shrug off harass in lane and sustain through skirmishes, making him exceptionally tough to kill the first time. The real strength, however, shows when he finally goes down. As Reincarnation triggers, a well-timed Overgrowth from Treant Protector can root the entire enemy team, turning their successful burst into a disastrous overcommitment.

This dynamic gives Wraith King a much more secure path through the early and mid game. He can farm more confidently knowing he has a global safety net. For the enemy team, it creates a serious problem in teamfights. They have to expend significant resources to kill him once, and then they are often left out of position and vulnerable when he comes back to life inside a field of roots. It forces a level of coordination that many teams struggle with, giving the duo a consistent, if not overwhelming, advantage.
