Nature's Prophet + Undying

Why this works

Forcing a five-on-five fight around Tombstone requires the whole team's commitment to protect it and brawl. Nature's Prophet, however, plays a completely different game. His entire strategy relies on using Teleportation and Treants to apply pressure across the map, forcing enemies to split their attention. When Undying wants his team to group up and commit, Nature's Prophet is often pushing a distant lane or farming. This leaves Undying's team fighting outnumbered during their most important timing, making it much easier for enemies to handle the Tombstone and win the engagement.

This fundamental clash of strategy means the team is always playing at cross-purposes. If the team groups to support Undying, they are wasting all the global pressure and farm acceleration that Nature's Prophet provides. If they try to play around the split-push, Undying is left feeling useless, unable to create the chaotic teamfights where he excels. Opponents can easily punish this by either forcing a fight against the weaker four-man squad or by sending heroes to shut down the solo Nature's Prophet, effectively neutralizing both game plans.
