How to play as Kai'Sa

When Twitch is missing, don't push far up or walk alone to catch a wave: he can wait in camouflage and open on you. Favor a recall while the wave is moving toward you, then step up again once he shows.

If both supports can engage, trade decisively around your support's crowd control or an isolated Icathian Rain(Q); avoid repeated short trades that let Twitch's lane sustain and scaling take over.

Ambush(Q) lets Twitch approach while camouflaged and grants him attack speed when he reveals; Venom Cask(W) slows and applies poison for Contaminate(E).

How to play as Twitch

Use Ambush(Q) to threaten Kai'Sa when she steps up, but avoid opening into her support's crowd control; once a safe all-in starts, Venom Cask(W) slows her so you can stack poison before Contaminate(E).
