Timbersaw's pure damage nukes can kill the tanky Tidehunter surprisingly quickly.

Timbersaw's Whirling Death is especially potent againts high strength heroes like Tidehunter.

Pierce the Veil makes Muerta ethereal, ignoring Tidehunter's physical damage completely while offering Insane amount of magic damage.

Muerta's other tools like The Calling can also make it hard for Tidehunter to position in fights , especially with The Calling's silence and slow not being easily removed with Kraken Shell due to it's AOE nature.

Healing Ward is a great way of sustaining through Tidehunter's Anchor Smash damage.

The high magic damage from Blade Fury allows early kills against Tidehunter.
