I'm Dave and i really like Assassin/Magic type champs and zed is one of my best here is why.

Zed is an attack-damage based assassin who has received massive amounts of popularity in professional and solo-q play. He is suitable to both mid,top and sometimes, even jungle. Zed is thoroughly rewarding with a ton of tricks and combos at your disposal meaning he never gets boring!

Pros


+ Best ninja in the game
+ Energy User
+ Easy farming champion because of Contempt for the Weak
+ Huge Burst
+ Decent wave clear for an assassin
+ One of the best splitpusher's
+ One of the most fun and rewarding champs Zed is an amazing champion with tons of reasons to play him. He has a plethora of tricks and skills at his disposal coupled with an enjoyable kit. One of the most rewarding champions to play who is not that hard to pick up (It was a Zed free week a couple of years ago, and I decided to play him, in that astounding game I went something like 28/7 .

Cons

-First times will not be perfect
-Easy to miss spells
-Lack luster damage without Death Mark
- Death Mark damage countered by Quicksilver Sash
-Consumes energy fairly quickly if spells are spammed
- Razor Shurikenis easy to miss
-Dynamic abilities like Living Shadow make him hard to play Not everything is luscious and green on the other side, this includes Zed! This ninja has drawbacks as well such as not being easy to play at first. However, the Pros outweigh the Cons and if you can get past these pesky problems you will enjoy success on Zed!

My Preferred Spells

Necessity

This summoner spell is universally useful to all champions, this applies to Zed aswell. Gap-close, gap-make, without flash the cake is hard to rise without the flour!


Zed is an assassin, and to kill you need that extra damage. So many times opposing laners run away with that slithering health bar however ignite can remove this risk. 400 true damage is pretty good!

Q

Razor Shuriken is Zed's 'bread and butter'. Since Zed is not restricted by mana, don't be afraid to hold onto it, when an opening appears go for the poke/kill. Use this ability to
Farm
Poke/Harass
Intimidate
Spam this ability, don't be afraid!

W

Living Shadow is what makes Zed 'unique'. This skill allows him to stay relevant in the meta because it is his 'mobility spell'. Coupled with mobility is the extra enhancement it provides to and . This ability helps with
Gap Closing
Running Away
Zoning
Double Shurikens
Second Shadow Slash
Allows creative ways to collaborate with Death Mark e.g. Living Shadow behind the target

E

This ability is so severely underrated. Most people will purposely run through shadow because they believe after there is no threat, however. has plenty of meaning full utility even after the damage.
A really underrated slow allowing for easier
Does a decent amount of damage
Is good to get in the mage's faces
Not the best but decent range to zone coupled with W.

R

This is what makes zed , zed . This ability, in my opinion, separates the good from the mediocre ones. Knowing when to back is crucial to the success of the Zed player. This vital ultimate provides with
'Meh' damage early game, however mid-game it starts to hold its weight
Is countered by items like
Very good for extra mobility
Duplicates effects of regular abilities aswell
Collaborative ways to use with
Good timing with invulnerability allows key dodges e.g.
Shuriken hovering over targeted head indicates imminent death for enemy. Port away at last second to look cool like a real ninja, unlike of course!

Top is okay in general however, he just isn't as optimal there as he is mid. Taking Zed into mid lane means he probably has a squishy to kill there. The lusciousness of the grass fades when going into top lane facing most likely a rugged hybrid beast mixed with damage and tank stats. The standard top laners I see in this meta the most are Riven, Irelia, Malphite and Gnar. Zed struggles against almost all of them mainly because they all have that mix of survive-ability and damage to kill Zed in the laning phase before you can kill them.

There is so much pressure for top lane Zed to go off. And when I say "go off" i mean like explode in the laning phase. Many top lane champions like Maokai and Singed scale into the late-game really well by being indestructible beings with stacks from Rod of Ages. If you're content with just 'laning' with them, you have lost the laning phase. It's already bad enough that your team doesn't have a sturdy, durable team member, but also that your rival laner will just scale into the cliffs of Everest.

I mean don't even try i saw people who can but they are pro in jungleing and you are not gona let kills for other lanes witch means you are bad at jungle you have top/mid (Pref Mid).

Zed's role in a team fight is to burst the enemy squishy (the champion which is weakest under fire however strongest when able to fire freely) for example, Corki. Your job as Zed is to divert all attention to you, kill them and run away safely.

However, not all super powerful things in league of legends have no counter play. Zed, late-game is easily countered by items such as Quicksilver Sash which renders your Death Mark damage use less. Once this happens, look at the scoreboard and aim for someone else to target, with a Zhonya's Hourglass on the enemy mage, don't give them first priority. It is possible to even peel for your Lucian instead of going for their Tristana, thus eliminating their front line more quickly than yours.

Thank you if you read it all it was hard to do it but i got a lots of help from http://www.mobafire.com/profile/a-express-584103 (aka A-Express)
