Hello!
My name is Fikso, I'm playing League since beta and my highest rank was Platinum 1.

Right now I'm playing this game casually just to kill some free time.
Since this game is going downhill each new season I just play Shaco support past 2-3 years because I truly think nothing can ruin it, even with the new rework.
My peak win rate in 20 games was 70% (in gold) but it also worked well against diamonds, and it shines vs one trick enemies who haven't encountered it yet.

When you play those baiting mind games with Shaco it feels like a different game and that's why I enjoy it.

-High CC
-High mobility
-If you die few times and get behind it wont have almost any effect on you beside ability lvl+little cooldown before lvl 9
-The safest escape from enemy/gank when around boxes
-High impact on team fights if you set boxes right
-If you win baiting mind games with your enemy you win game

-You need to be low on health for perfect baits to work
-2 active items
-Learning to control enemy minions path to save boxes
-If your ADC calls you a troll and won't cooperate it makes things harder because they have to help you maintain minion waves
-You have to be experienced player to predict enemy path before they even show up

The bread and butter.
If there wasn't Zhonya's Hourglass support or AP Shaco would be bad.
When you combo stasis effect with Hallucinate you are invincible for 3 seconds. In that time if you are low on health and they are sitting on you, you just buy time for your ADC/boxes to do some damage or even score a kill (same thing in teamfights) and just Deceive out like a real OG.

Hextech..
There's a holy trinity of Taunt, Wave clear and Kill.
-When you wanna bait them and they are playing smart just charge them with hextech, even if they're full hp, works most of the time.
-When you're solo split pushing bot while your team is losing team fight on mid you can one shot minions with hextech as long as you position good for faster pushing.
-If someone survives Two shiv execute, Hextech+Luden should do the trick for finishing touches.

Deceive
-Qucik cast Q + Teleport if you have it, you can teleport during stealth, but you need quick fingers.
-Qucik casting Q + hextech with keeping the stealth doesn't work anymore.

Jack In The Box
-Sometimes when you're low on health and about to recall, try to set 2 boxes under tower and bait them to flash dive you, you get the idea.
-After rework oracle wont disable your jacks and enemy will have to kill them in order to not get killed.
-To get the most of it, try to bait enemy in small path between 2 boxes, so when he triggers 1 he will get feared into the other one

Hallucinate
-While you are cloning you are invincible, you can use it to deny things such as Ignite damage tick, Karthus, Zed, Fizz ultimate, Dragon knockback.
-If you position correctly you can also use your ultimate to teleport over small walls. Keep in mind that after you ult you get pushed on your right side and clone on left, its the easiest to practice if you focus on your face and aiming right, start with smallest walls you can find.
-When enemies don't have vision on you, you can use your clone to start teamfights, they will use some abilities and if you manage to fear them its the perfect opportunity for your team

You want to hard push bot. Place your children behind and near your minion wave, and protect it. If enemies decide to engage you they get feared and damaged. If they try to gank you, same thing. If you're full on mana throw a dagger. If they tower dive you, Deceive into them, place a box behind them, ult and ez pez.
You can also save your ADC if hes being focused by sitting on enemies, giving them all and buying time with Zhonya's Hourglass.

You basically make a field of boxes which means safety for your team in case enemies engage first. It can also be used in case your team engage fails.

If you're like me and you think this game is going to hell, give it a try and have fun!

I will also add some clips of Hallucinate teleporting and master baiting soon.

It just breaks my heart when I see all these new post-rework support Shaco guides on youtube, so I had the urge to make this little guide asap.
