Status of Updating Guide
I'm kinda back from the break so yeah this will be getting a bit more in terms of the chapters. I'll return to the matchups later but for now I think it's better to write the basics of Jayce than matchup specific stuff.
Who am I?
I have no idea what happened to these pages but I somehow copy and pasted matchups into here. Hi :) I'm a silver player who enjoys Jayce, Lissandra, and more recently, Azir and Kayle. I currently have M7 and 100k+ mastery points on Jayce. This was originally a guide called "Balanced" when I just made the guide for fun, but now I like making guides so I'm revamping this one. I hope you enjoy this guide and I wish you luck on learning Jayce :).
Pros and Cons of Jayce
Pros
Multiple Playstyles
Good Damage Output
Gets Stronger With The Player
Strong Early-Mid Game

Cons
High Skill Cap
Multiple Playstyles
Mechanically demanding
Sort of falls off late
No Ult
Team Comp Reliant
Not The Best Team Fighting
Squishy
Why does Jayce have a high skill cap?
Due to Jayce being a transform character, he naturally has more abilities to use. At LVL1 he already has 2 abilities he can use. This makes him have 6 abilities instead of the normal 4. Not only does he have more abilities but he can only have 3 of them available to him at all times. So for him to get the access to the other 3 he must input a button and continue his combo. This goes for all transform characters, but it doesn't mean anything less on Jayce. It honestly might be worse on Jayce as he is a burst character meaning that the player must be able to correctly input the whole combo quickly.

Another reason why Jayce is so hard to play is due to that availability and freedom of his kit. He has poke, disengage, speedups, dive, outplay potential, ranged and melee forms, and good wave clear. He may seem broken, and he is when he's used to his full potential. However, to get the maximum potential out of his kit you have to understand how to play and adapt to all of his playstyles. Jayce is an extremely flexible character, and to master Jayce you must have good mechanical skill, decision making, adaption, understanding of the matchup, and the ability to play multiple styles of one character. A true master of Jayce will be able to break the game and demolish people with his flexibility.
Abilities
HAMMER FORM

"Hextech Capacitor" P:
Each time Jayce switches between Hammer Stance and Cannon Stance he gains 40 bonus movement speed and ghosting for 1.25 seconds.

"To the Skies!" Q:
ACTIVE: Jayce leaps to the target enemy's location and smashes his hammer on the ground upon arrival, dealing physical damage to all enemies within an area and slowing them for 2 seconds.

"Lightning Field" W:
PASSIVE: Jayce's basic attacks on-hit restore mana.

ACTIVE: Jayce surrounds himself with an electric field for 4 seconds, dealing magic damage each second to all nearby enemies over the duration.

"Thundering Blow" E:
ACTIVE: Jayce swings his hammer at the target enemy, dealing them magic damage, capped against monsters, while also marking a location 500 units away from him in the direction of the target, pulling them to it.

"Transform Mercury Cannon" R:
ACTIVE: Jayce transforms the Mercury Hammer into the Mercury Cannon, receiving access to its abilities, becoming ranged with 500 attack range, and empowering his next basic attack to reduce the target's armor and magic resistance by 10 / 15 / 20 / 25% (based on level) for 5 seconds.

Jayce begins the game with Transform but cannot increase its rank. Instead, his basic abilities each have 6 ranks.

CANNON FORM

"Hextech Capacitor" P:
Each time Jayce switches between Hammer Stance and Cannon Stance he gains 40 bonus movement speed and ghosting for 1.25 seconds.

"Shock Blast" Q:
ACTIVE: Jayce fires an orb of electricity in the target direction, detonating upon hitting an enemy or reaching the end of its path to deal physical damage to it and other enemies within the area and briefly grant sight of the area.

If the orb passes through Acceleration Gate, it supercharges, instantly increasing its speed and remaining distance and causing the subsequent blast to be larger and deal 40% increased damage.

"Hyper Charge" W:
ACTIVE: Jayce gains 300% bonus attack speed on his next 3 basic attacks within 4 seconds, with each one dealing modified damage.

Hyper Charge resets Jayce's basic attack timer, and the modified damage is affected by critical strike modifiers.

"Acceleration Gate" E:
ACTIVE: Jayce deploys an energy gate centered at the target location for 4 seconds, granting sight of its area and granting all allied champions who come in contact with it, including himself, bonus movement speed that decays over 3 seconds. The buff is continuously refreshed inside the gate.

"Transform Mercury Hammer" R:
ACTIVE: Jayce transforms the Mercury Cannon into the Mercury Hammer, receiving access to its abilities, becoming melee with 125 attack range, gaining 5 / 15 / 25 / 35 (based on level) bonus armor and bonus magic resistance, and empowering his next basic attack to deal 25 / 65 / 105 / 145 (based on level) (+ 25% bonus AD) bonus magic damage.

Jayce begins the game with Transform but cannot increase its rank. Instead, his basic abilities each have 6 ranks.
Combos/Tech I remember
Cannon Form:

Basic Poke:
Q
Very simple ranged projectile for whatever you need it for. Whether its grabbing CS or punishing your laner for walking up, this is just a basic damage projectile.

Gate Q:
E > Q
Place the gate in front of yourself and throw Q through it. Throwing E before Q makes time to cast both spells decrease and makes it easier to place your gate. To poke you don't necessarily need the gate as it will increase the mana cost but it will enhance the power and range of your projectile. You can use this for the same reason as just throwing a Q.

Basic Spell Rotation:
E > Q > AA > W > AA x3
This combo branches off of the poke combo by adding auto attacks. This is a heavier version of the poke combo and is just optimizing damage without having to go in hammer form.

Cannon Form All-In:
E > Q > AA > W > R > QW > AA x3 > E
This is the all-in combo starting from Cannon Form. Starting in Cannon Form means that you get 3 melee autos off faster but in return you can't kite in ranged form after you're done with the combo.


Hammer Form

Simple Melee Trade
QW > AA (optional) > E
We primarily want to Q onto the enemy because it will get us directly on top of the enemy to AA them. However, you only need to Q onto a nearby minion because even if you don't hit the direct Q the AoE slow can still hit and allow you to trade.

Melee Trade Swap
QW > AA (optional) > E > R > AA
This is the same thing just if the enemy can't engage onto you easily and the extra AA gives a slightly stronger trade.

Melee Form All-In
QW > AA > E > R > EQ > AA > W > AA x3
This is the melee all in combo. This combo allows you to kite your enemies after bursting them in return for not being able to quickly melee attack your enemy.


Tech

Surprise Projectile
Cannon Form Q > Flash
For when your enemy is easily killable from a ranged Q but you either want to make them react or you want to easily close the gap due to the range limitations. You can also add the gate into this combo but it will take a bit more time if you want it, and the tech would now be Flash > EQ. You could also just fire Q and then flash and put the gate before the Q's range ends making the tech Q > Flash > E.

Mobility Cancel E
Hammer Form E
If someone is dashing onto you say like an Urgot, timing your Hammer Form E correctly has the ability to cancel their dash and will send them as far as your E will take them.

Q Animation Cancel
Hammer Form Q > Emote
I don't even know if this is practical but if you Hammer Form Q onto something and then do an emote/dance you can stop the animation. I think it still does damage but I haven't actually used this before.
