PROS
One of the best scalers if not the best.
Can build both ad/ap
Always a good pick/good blind pick.
easy to farm with.
Her kit is everything a adc needs.

CONS
Weak without upgrades.
vunerable in lane if you got afk support.
Takes some time to get used to her kit.

lv. 1 You always start with Doran's Blade just to get the Q upgrade as fast as possible.

You always want to get Serrated Dirk before(IF YOU DONT HAVE ENOUGH FOR >> Noonquiver because first it gives you armor pen, but also if you farm even with their adc and go back with 1100 gold it would be a awkward recall for them. Focus on getting your Q upgrades with Dirk > Noonquiver/Pickaxe > Pickaxe/noonquiver.

And even you have your Kraken Slayer/ Galeforce and Serrated Dirk
If they have more meelee champs that prob will stick to you or needs to get close to you can build hurricane before finishing collector and if it only assasin or 1 person that will stick to you, you should go for Phantom Dancer

The most important about kaisa is how you use her Q, and it's a lot of her whole kit that makes her really good compare to a new kaisa player.

A good kai'sa mostly almost get her Q isolated.

Her ulti is a auto cancel so you can always get a free auto before you ulti.

When you have you E upgrade you can get a free auto before you go into stealth aswell.
