Your Win Condition
Tahm Kench is a losing skill matchup. The goal is to make it playable by avoiding Warden's Mail.
General Strategy
Tahm Kench has the option to build Warden's Mail, which makes your life unplayable.
Trading Patterns
Stand behind minions to avoid his Q (Tongue Lash). Tahm Kench's W (Abyssal Voyage) is bufferable: as he is coming up from the ground, press E to buffer the knock-up and grab him. Tahm Kench can E (Devour) you out of your E animation. If Tahm Kench ults you while your R2 is embedded, you can activate R2 from inside him, teleporting away while dragging him with you, and he explodes.
