How to play as Tahm Kench
Do not use Abyssal Dive offensively while Yorick still has Dark Procession available; clear ghouls first and save Q for Yorick or the Maiden when they are exposed.
If Yorick has the push, farm near your turret and avoid dying to a cage follow-up; Tahm is more useful in teamfights when Yorick has left his ghouls and Maiden behind.
Yorick's ghouls can intercept Tahm Q, which hits the first unit in its path, and Yorick W can trap Tahm after he dives in with Abyssal Dive.
