First of all, I had to do a lot of math to find the perfect item build for Kai'Sa.

To get your upgrades, you need:

100 AD to upgrade your Icathian Rain

100 AP to upgrade your Void Seeker

100% Attack Speed to upgrade your Supercharge

When playing Kai'Sa as an AD Carry, you should ignore the Void Seeker upgrade for at least four items.

Your runes, like Legend: Alacrity, or stats from trees like Precision, do not affect the count.

The only stats that count besides your items are your level-up stats. You will get:

15% Attack Speed and 9 AD at level 10

20% Attack Speed and 12 AD at level 12

25% Attack Speed and 14 AD at level 15

So, for example, if you want to have both upgrades at level 13, you need to buy around 80% attack speed and 90 AD.

The best item build path to activate the upgrades as cheaply as possible while still granting valuable stats looks like this:

Statikk Shiv or Kraken Slayer

Guinsoo's Rageblade

Nashor's Tooth

Your AD and attack speed requirements should be fulfilled now. For the next items, focus on AP to finalize your build. Cryptbloom or Void Staff are great options for a W-based poke build, while Zhonya's Hourglass is rather defensive and can save you from many deaths since it synergizes well with your R ability.

Lethal Tempo seems to be the best all-rounder choice for your keystone. The other runes are pretty common and have been the best options for a while now: Presence of Mind, Coup de Grace, and Legend: Bloodline. The sustain granted by Presence of Mind and Legend: Bloodline is very valuable and makes your laning phase much easier.

For your second tree, Inspiration offers you Biscuit Delivery and Magical Footwear for sustain and to save some money. This is handy because the earlier you hit your stat breakpoints, the earlier your abilities upgrade.

Second Skin Passive: It's the opposite of Miss Fortune's mechanic. Keep attacking the same target to maximize the damage from your passive. If you own Runaan's Hurricane, you can apply plasma to multiple targets at the same time, unlike Vayne, where changing the target removes all stacks.

Icathian Rain Q: Try to clear the enemy minions before using it to maximize its damage to champions. When engaged by a tank in a 2v2, try to get closer to their ADC before using Q, so their ADC receives more damage than their tank. You can cast Q while moving, allowing you to trade with enemies and last-hit at the same time, or take last-hits with Q and auto-attack enemies when they go for a last-hit. This simple mechanic helps you win trades.

Void Seeker W: W doesn't scale very well with AD, but even with one point in it, it deals a lot of damage and is crucial for preparing your ult. Since it applies plasma on enemies, you can use your ultimate to engage or escape from a bad position. Additionally, fewer auto-attacks are needed to trigger the last stack of plasma and deal a lot of damage. You can reveal the most annoying champions like Vayne, Twitch, Rengar, and Evelynn with W. Given that you don't have to manually aim your Q and have a reveal on W, Kai'Sa can be a strong counter to Vayne.

Supercharge E: E is a steroid that boosts your attack speed after charging up. Make sure not to use it during a fight because Kai'Sa will stop attacking while charging. Use it as often as possible when returning to lane to benefit from its bonus movement speed. The ultimate goal is to take advantage of the invisibility you get after purchasing enough attack speed, enabling you to make big outplays, funny escapes, and secure kills. Always use it before a fight starts and juke your enemies with your invisibility.

Killer Instinct R: First of all, an ultimate that doesn't deal any damage may sound lame for an AD Carry, but trust me—this ability is powerful in its own way. To make the most of it, you need to land your W Void Seeker. This 2-spell combo allows Kai'Sa to be the first ADC who can follow up and help teammates on other lanes, similar to Galio, Shen, or Twisted Fate. You can save teammates, pick up kills, and your enemies' bot lane won't be fast enough to follow you. Always keep an eye on your jungle and mid lane. You can also chase down running enemies with W Void Seeker + R Killer Instinct to secure kills. Even in hectic teamfights where you can't benefit from your W's range, it's a useful tool that protects you and allows you to reposition, helping you avoid dying in the late game.

Kai'Sa is one of the strongest duelists in the game, offering both physical and magical damage and the ability to destroy tanks within seconds. Her adaptability makes her a versatile and powerful champion. In my opinion, Kai'Sa is one of the most flexible and strongest champions you can imagine. Even if the AP build that allowed you to snipe people from across the map is less viable now, she remains a top pick.

Her mixed damage output and ability to reposition with her ultimate give her a unique edge in both teamfights and skirmishes. She excels in various roles, whether you're building her as a traditional AD carry or experimenting with hybrid and AP builds. Her powerful abilities make her a formidable threat at all stages of the game.

Given her versatility and raw power, I highly recommend blind-picking and maining her in ranked games if you are experienced with her. Mastering Kai'Sa will undoubtedly elevate your gameplay and provide a significant advantage on the Rift.
