With the introduction of new patch and items, it looks like Giant Slayer will be the strongest item of the patch. In 9.19 there is a strong chance that no item will provide "wearer's attacks cannot be dodged" buff. So only way to get this buff will be having 4 wilds on your team. To prevent losing against Yordles or some Phantom Dancer built teams, having 4 wilds along with your slingers actually a great idea. They also provide attack speed stack on hit which also helps on item based (I'm talking about Guinsoo). In this build you don't have to worry about leveling 3 your Tris or Lucian, when you have 2 star of al your units you're good. Try to pick B.F. Sword or Recurve Bow for Giant Slayer, if not just grab a Giant Belt or Chain West to build Red Buff but don't forget in this build there is no too much Giant Slayer, build as many as you can. Start your team whatever you find first from Wilds or Slingers. Jayce and Graves in this build are not a must but they you can pick GP (his barrels apply on-hit effect don't fear building Giant Slayer and Red Buff on him) instead of Graves and any shifters instead of Jayce (He becomes a monster with Wilds when equipped with any number of Titanic Hydra's, also he activates the Hextexh buff which makes him the best option from other non wild shapeshifters). On Lucian my suggest is building cc items on him, you won't have the chance to build each of the above items but atleast try to build Hush (against any comp this item will help you to win the game) and Sword Breaker (only needed against Kassassin and Ranger builds) on him. Remember wild units only here for their buffs so don't rely on them. They can stay at 1 star even in late game but atleast have 2 stars of each slingers you have and don't forget 3 staring them is not necessary. When you 2 star them focus on leveling up to 9 as fast as you can. To find Jinx and Gnar wait until lvl 7 which is the best way to roll for finding any 4 golds unit. Until lvl 8 you can stay on 4 wilds 3 shapeshifter and 2 slingers but when you hit 8 put your other 2 slingers on the board.
Here is a game i played with the same build:
New Void Kassassin:
Using Kassadin as your main unit by giving him a Youmuu's Ghostblade (Spatula+B.F. Sword) and a RFC/Rapid Firecannon (Recurve Bow+Recurve Bow) alongside with Rek'sai or Cho'gath plus 5 other sins including Kha'zix and Kai'sa and only one of the Ninja/Sin unit which are Zed and Akali gives you high chance of finishing at top 4 opportunity. You have to focus on making your Kassa 3 stars by rolling before hitting level 5 and 2 stars Kha'zix and Rek'sai, by doing this you'll probably be at bottom of the lobby in early game which is actually good to finish your ghostblade early and if you lucky enough you'll already have 3 star Kassa before hitting level 5 or 3 or 4 rounds after you hit level 5.
At the level 4 you should have 2 voids(Kassa and Kha) and 3 sins (Kha, Zed and Pyke) on your board. After transforming your Kassa to a sin your goal is saving your gold by not rolling at all until you have 50+ golds. By this process you should focus on making your other sin units 2 stars. After saving gold you should spend it to level up to 8 (it was 7 at 9.18 patch) without losing that 5 gold tax, simply just keep your 50 golds and spend whatever your income is. After hitting 8 you will have high chance of finding Kai'sa, Cho'gath and Akali (Zed can be used instead of her to allocate gold for increasing chance of finding Kai'sa). There is 2% chance of finding 5 gold unit at level 7 if you want to try your chance you can find Kai'sa and complete your build.
With the new void trait you should use Kassa and Kha and avoid from using the third void unit which is Rek'sai at early game if you can't use four of them. That way your void buff will only activated on Kha or Kassa until you find 4 of them. You must use your last item slot on Kassa for a deffensive item in order to protect him from some unwanted situations, like hitting by a ghost, one hitted by Draven, stunned by any unit etc. My suggestion is having either GA for ghost, PD for Draven or new item Quicksilver for preventing any cc.

If you lucky enough to find Kai'sa at level 7 then you can build the comp below. *Items on Kassa and Kai'sa are more important than Pyke and Zed.
Ranger/Glacial/Knight/Void:
With the introduction of Kai'sa and change on void trait in the new patch an already strong comp, Ranger/Glacial, is stronger than ever. You can now remove the weakest unit in this comp, Vayne, and replace her with Kai'sa at the late game whenever you find her, probably the strongest unit in 9.19. Your main carry is still Ashe in this comp so build items on her first then build on Vayne. When you find Kai'sa sell your Vayne and give items to Kai'sa.
At the start of the game use a Ranger/Knight/Noble comp.
Hitting level 6 before anyone else to increasing your chance of finding Ashe and Kindred is too important in this build. That way you can play mid game without getting hurt when you complete 4 rangers.
Best way of finding Kai'sa is rolling at level 8 with 5% chance. So when you have 2 stars of each unit expect Kindred you should start investing gold after level 6. Until level 8 pick other important units like Seju, Braum, Voli and Rek'sai/Cho'gath. Until level 9 there is 3 way of using your units, you can either use 4 glacials and Morde with 4 rangers that way you will have knight, phantom buffs or use 4 glacials and Rek'sai that way you will have brawler and void buffs or the last one keeping Braum at bench and having 3 glacials with void, phantom and knights buffs activated. You can rotate these comp to beat different opponents by guessing which opponent you will face next with the new matching system.

Draven and his tank mates:
Using Draven as your only carry by giving him RFC, Bloodthirster and eaither GA as defensive or Guinsoo as offensive item by your choice and building a meat wall with 6 knights and 2 guardians makes him unreachable by your opponents. This build can easily countered by Yordles so if there is someone going Yordles you should accept you won't win against that opponent.
To fully complete this comp you must not roll until hitting level 7, not even a single roll. Just save every gold. Grab every knight unit until you 2 star them by that time and don’t even think of 3 staring them, trust me its not even worth your golds. At the first rounds of the game try to build a 3 nobles that includes Garen, Vayne and Lucian with 2 knights. When you hit level 5 grab a Braum and put him in frontlane. You can stack your Draven items on Vayne
This is how your comp should be at level 5.
Try to stay above 50 golds until level 7. When you hit level 7 with 50 golds roll until you find Draven and stop rolling. If you already find Leona while you roll for Draven you can sell your Vayne and Lucian and rearrange your team like this. Feel free to add Seju instead of Morde if you already find her.
Now its time to saving golds again. Stay above 50 golds until level 8, when you hit level 8 with 50+ golds you should roll until finding 2 star Draven, Seju, Leona and Poppy. Also you'll have 5% chance to find Kayle this way.
There is a good side of this build, which is finding an already completed Knight's Vow at level 8 from carousel that before the dragon round and giving it to Leona and finishing your build at level 8 without last knight and having all this money to roll freely to 2 star your tier 4 units and finding Kayle. Don't forget your only carry is Draven in this build, so focus on completing items for him first. With Thornmail and Warmog's Braum can be a hidden carry for your team.
