Pros / Cons

Pros

+ Third longest range in the game (650).
+ Great range; it allows you to poke and move back, before they get to touch you. "Hit and run".
+ Great damage early, mid and late game.
+ Amazing harass abilities.
+ Easy to last hit with.
+ Wonderful passive. If used correctly, it will help you gain control over the lane and scare your enemies.
+ Piltover Peacemaker got a nice amount of damage, and is easy to aim.
+ Great zoning with Yordle Snap Trap, and if placed correctly can help you get away from a sticky situation, through lurking them into a trap or avoid a gank.
+ A nice escape/chase mechanism and a decent movement speed.
+ Can finish off low health enemies in a great distance.
+ With the correct position, you can change the outcome of a team fight.
+ Extremely fun to play, you will be in love with this Champion.

Cons

- A very low mana pool.
- Squishy.
- Focused in team fights (especially if fed)
- Yordle Snap Trap can be walked around, due to visibility.
- Ace in the Hole isn't reliable if there is more than 1 enemy in the lane. Enemy champions can intercept the bullet for their ally.
- Spamming abilities will oom you quickly, try and avoid spamming them unless you're sure about hitting. - On the other hand, who doesn't oom quickly when you spam abilities? Except people like Garen and Trynd (them op people).

Skill Sequence


It's pretty simple.
Start the game out by picking Yordle Snap Trap(W), to prepare and place up traps before the enemies come to the lane. You should pick this ability first and max it last. Do not touch it again until you have no other options.
Then pick Piltover Peacemaker(Q) And max it 1st.
You should get 90 Caliber Net(E) around level 4, unless you fear an early gank from the enemy jungler, then pick this in level 3 for a brief escape mechanism. Max it 2nd.
By level 6 you WILL pick Ace in the Hole(R) Always level up this ability when you can, its your ultimate! Max it 3rd.

Abilities


Headshot

Caitlyns passive skill. I really love it, and find it awesome for harassment and farming.
This passive makes Caitlyn really strong in top and bottom because of the bushes.
If you auto-hit a minion out of a bush Headshot will grant 1 stack per shot, but if you stand in a bush 1 hit will count as 2 on the stacking. So use your Yordle Snap Trap to scare the enemy champions out of the bush and stand in the bush while trying to stack it up.

BE AWARE THAT ENEMY ALSO CAN SEE WHEN YOUR PASSIVE IS ON THE 7TH STACK Use this to scare them away and zone them. People will step away when they see you have it ready.

As you can see above on the picture, her hands glows shiny when Headshot reaches the 7th stack.
A small tip when pushing the enemy turret - When hitting the turret you gain stacks, but it won't use the final stack on the turret, so try and land the 7th hit on the enemy champion and go back to avoid a turret hit, then re-do the process.

Piltover Peacemaker

This spell is great in so many ways.
Harass in a safe distance.
Push
Farm
High damage

A skill-shot might not always hit, but when you hit with Piltover Peacemaker they feel it.
Do not spam this spell, I repeat DO NOT spam this spell. It drains your mana if spammed.
You can use this from a safe distance, but if you are using it to harass the enemy champion then try and hit as few targets as possible.
The damage is decreased by 15% for each target it hits up to 40%.

A tip when using it - When throwing it try to place it a few inches behind them, and move forward to place an auto-hit on them. If they wish to dodge Piltover Peacemaker they will have to step forward to dodge it, and it will allow you to hit them 1-2 times. Try and see if you can time this together with Headshot for max. damage.

Another tip - If the enemy steps in a Yordle Snap Trap use Piltover Peacemaker since you're almost 100% sure to hit the enemy champion.

Yordle Snap Trap

Early game these traps will do a lot for you through the laning phase, but they slack late-game and won't be worth much.

But they are so amazing in so many ways, which I will go into details about now.

You can see these traps so they can easily be avoided which makes them useless. On the other hand, they can be hard to see in the bushes so try and place them there, in a team fight they might 'seem' useless but they are not - Remember that in the team fights the opponents might not pay attention to the traps but their targets, so you can easily plant them and take one out when they step on it.

When an enemy steps into one of these traps, he/she will get stunned for 1.5 seconds, use this opportunity to harass.
It functions a lot like Nidalees traps except for the fact that Caitlyn got CC, the reason they remind of each other is due to the vision it grants.
Another thing they can be useful for is face checking.
Do not face check a bush, use your trap - It will grant you vision around the trap for around 0.5 seconds, which should be enough to tell you if they are in the bush or not.

Early game these traps are actually really strong. Around 80 damage in level 1, which is a lot that early. Imagine if someone were silly enough to step into 3 of those in a row (it happens). He/she would be down on 50% before the minions even spawned which would grant you a good start.

Even if I go bot lane I like to rush mid before the game begins and place 3 traps to help our mid-carry get a better start by zoning theirs.
I hope adding this picture will show you what I mean
This might not seem as a big problem to you, but think about it. You can barely walk through them, without getting hit by one of them. Your mid-lane will love you for it!
But you can also do this on other lanes as well, and if used correctly you might even stop a gank.
Where I like to place traps in my own lane:
Trap 1 is placed in my own bush, if they chase me down and I need some kind of escape mechanism, they will usually step through the bush and if they decide to avoid the trap, you will grant 1-2 seconds more to flee which might make a difference on surviving or not.
Trap 2 is placed in their bush to zone them, and make them stay out of the bush and closer to the river.
Q: Why closer to the river?
A: Well, it lets me have a view on where they are and I get control over the bush. Easier to go out and poke, then step back in before they get to react, if they decide to react I will get the first shot since they have to step inside the bush before getting vision on me.
And by getting them closer to the river, I also make them more vulnerable to a gank.
Trap 3 is usually placed in the mid bush in the river as most junglers like to wait in that bush until their team mates are ready for a gank.
Where to place traps, when in fear of getting dived, this is the perfect bait and can often give you a kill without dying:
You can use these traps everywhere on the map, but the following are my most recommend (if you start in blue base):

90 Caliber Net

90 Caliber Net is mostly used as an escape tool. You can knock yourself back, mostly used to increase the distance between you and your opponent. But a decent Caitlyn will also learn to master this ability, in more ways than just fleeing.
90 Caliber Net can be used for chasing as well. It also slows down the enemy on impact, so try and see if you can hit someone with it in the process, to gain more time to run.

What makes it so epic according to me, is the way you can go through the walls with it (Not every single every single wall). At certain places of the map, Caitlyn can push herself through with the use of 90 Caliber Net.



This can be done a lot of places around the map, it can be tricky sometimes to find the correct places, but it can spare you the waste of flash. For example if you solo dragon, stand close to the stones so you can instantly jump away instead of dying. Stand the same way, as shown in the picture above.

Ace in the Hole

This ulti is amazing to finish off fleeing targets. But it got some cons as well.

Pro's:
+ Long range
+ High Damage
+ Often gets you a kill in level 6

Con's:
- 2-seconds charge time making you unable to move.
- Might not always hit your primary target, if another enemy is willing to take the hit by stepping in front of your target.
- If the enemy dies before the 2-seconds charge, it will automatically get cancelled. (THIS WILL RESET YOUR COOLDOWN, SO NO WORRIES)


Keep in mind not to randomly use this spell, save it for a kill.
A small tip when using Ace in the Hole - Do NOT use this in a team fight, you risk getting into a bad position, use it when the fight is about to end on the fleeing enemies. Since it might also be difficult to actually get a kill with this, when the tank can block it for your primary target.

Make sure your support carries Clairvoyance to help you with the ultimate.
If you can ask your support to CV and ping, then thanks to the incredible range of Ace in the Hole you might get the kill even from a far distance.
