Ed'Sai

The price of void rush completely jumped so the deck got from 38$usd to 77$usd.

wait a month and the hype will pass.
Also, considering switching void drones for 3*Noxian Emissary, turning the deck into a 6/6 rune split to help with empower and the sideboard power costs.

Basic guidelines for the best guide you'll ever read:
You feel the need to mock people playing with 400$usd decks? Make them quit the game entirely?
I got you.
To make it possible, you don't really want to hold, but don't mind it either.
Just rush in to conquer and die to reconquer as many times as possible with the smallest units possible on every turn while making them waste their hand while you play off the top of your deck.
Try to keep at least 1 Yellow rune when recycling with Void Rush, since you have less than Red ones.
Build a strong army in your base and conquer with 1 unit at a time over and over. That will make some players fume...
which is very much worth 40$.
Conquering brings more units while also keeping a full hand. Dued to the blessings of our beautiful Queen; Rek'Sai.

Don't fight for board control.
Fight for conquer triggers.
Every conquer is another unit, every unit is another conquer,
then every reconquer is another chance to bury your opponent under Rek'Sai's endless swarm.

Easy wins.

Now go bully some Yis, Irelias and Dianas handling your nearly exclusively common cards while their deck is worth 2 monthly car payments.

Battlefields:
-Candlelit on first round to make your Rek'Sai(Legend) ability even more useful while your opponent hasn't yet side decked.
-Seat of power lets you draw on double conquers and kind of forces your opponent to separate their units. Which gives us the advantage since we have many strong cheap units very early.
-Zaun just lets you draw on conquer. kind of never a bad thing but you are also able to discard a drawn Void Drone so.. makes sense.

Long live Queen Rek'Sai.

Gameplan:
1st to go Because you're a winner:
-Mulligan :
get a turn 1 and 2. that's it.
reroll Void Drones for sure, Undertitans if you need a turn 2.
do not overdo it.
drawing Void Drones or Undertitans instead of revealing them with rek'sai(Legend) or Void rush because of overdoing it in the mulligan makes you reevaluate your whole life decisions.
-turn 1:
play a 2 cost. there's a 95%-96% chance that you have at least one in hand if you've followed the mulligan guidelines. If you're that unlucky 4,5%, I apologize and am sorry. Maybe just stand up, give up, burn the deck and put out the fire with your tears. I'm sure you didn't deserve this.
-turn 2:
As soon as it's your turn, conquer your own battlefield. they're good for you. you picked them yourself like a big boy by copying this majestically cheap list. Conquering Seat of Power may provoke the opponent to reconquer it, making it easier to double conquer next turn to draw a card. Keep in mind that their battlefield may have more impact tho, don't take this advice as a ''must''.

Activate Rek'Sai(Legend) to chain with the battlefields appropriately to have units in base ready for another easy conquer on your turn 3.
-turn 3 and over:
Play a unit or spell before conquering for Noxus Hopeful's Legion's trigger. If you don't, I'll put you on a watchlist for self-harm.
After playing a card like a pro, conquer the battlefield to activate our Queen's ability and get another unit in base.
you're an engine rush deck, so get you some more units directly from the top deck and rush in to win, we ain't afraid of early crashouts.

2nd to go Because at least you've tried:
-Mulligan:
never keep Void Drones or Undertitans still as explained in 1st to go.
Almost any other units/spells will do.
You have a 3cost in your champion zone anyways.
-turn 1:
Play either:
Faithful Manufactor to pressure for 2 points on turn 2 if they haven't played anything
Daring Poro for a single 3might unit on attack next turn
Rek'sai(Champion) from the champion zone for a single unit 4might on attack next turn
any other units
in priority order.
-turn 2:
pretty much the same gameplan as ''1st to go''.
altho you also have the ability to try and contest their conquer with a cheap spell to maybe play Noxus Hopeful on conquer.
if you suspect your opponent has a response to it, just conquer the free battlefield and activate your beautiful girl, Rek'Sai to build up your base.
-turn 3 and over:
still the same as ''1st to go''
very straightforward gameplan.

Side deck:
-3 Hidden Blades if you need to draw vs other swarm decks or have specific threats Such as Vilemaw(Green), Irelia, Hwei, Yi, Vex(Purple), you get the idea.. or against control decks by killing off your own unit instead after they've paid the cost and letting you draw 2 for a unit that would've died anyway.
-2 Long-Sword if they counter spells. it's a gear, not a spell. it stays in play for future conquers too.
-2 Facebreaker against other early range decks to stop them on their attack or reduce a huge oppressive unit to zero to not lose 4units in a single combat
-3 Salvages against aurora and gear heavy decks and letting you draw for a cheap cost.
