Nature's Prophet vs Undying

How this matchup plays

Trying to fight near a Tombstone is a disaster for Nature's Prophet. His Treants become a liability, as each one that dies near the Tombstone spawns another zombie to overwhelm him and his team. This swarm makes it impossible for Prophet to contribute his own right-click damage, forcing him to flee or die. Beyond that, every unit he summons simply powers up Undying's Soul Rip, turning it into a massive burst of damage or healing. Even without his summons, Nature's Prophet is a naturally fragile hero who gets crippled by a few stacks of Decay, making him an easy target in any skirmish.

This dynamic leaves Nature's Prophet with no good options. If he joins teamfights, his summons actively help the enemy Undying control the engagement. If he tries to split-push instead, he leaves his team to fight four-against-five into some of the strongest teamfight tools in the early and mid-game. Undying dictates a pace and style of fight that Nature's Prophet is completely unequipped to handle, and he lacks the durability to survive being the focus of Decay and a zombie swarm.
