Hi everybody this is my first guide so enjoy it!
Shaco is one of my favorite champion to play, he was fun all the game and you can make very great score with it!

Why play Shaco:
-with shaco you can kill an enemi and escape ganking easiely;
-funny champion with her many strategie;
-anoying ultimate;
-hard to kill because you can escape very fast of squishy situation;

Sad:
-hard to play for a beginer;
-with my build, if they are more than 2 you gonna die (exept if you run);
-Shaco didn't stop to laught all the game;
-if the other team take oracle or a vison ward, you gonna have some dificult;

Sumoner's spells!

What I recomend:
Heal: I choose this one cause with my build you don't have a lot of healt

Flash: I love flash because when your Deceive is in cooldown, it give you the time to refresh it and escape.

What you can take alternately:

Exaust: You can take this spell to slow your target but Two-Shiv Poison alerady make it

Ignite: If you want make dommage in early game

Gost If you like to run

teleport If you dislike to run

What I don't recomand:

revive: ...

Rally: if your target run you gonna use this spell for nothing

Fortify: no utilities for you

Smite: ...

Cleanse: normaly the time to click on the spell all debuf are alerady disapear

Clarity: Blue buff is for you!

Early in the game:
I begin with the cloth armor to give you some protection early take potion of you need I recommand 2 or 3 red and 1 blue but you can choose other. Begin into the bush and put all jack in the box of you can, stay in it and wait for the first enemi who fall into your trap and finish him. OR begin by put 3-5 jack in the box at the golem to take the blue buff its generatly easy but DON'T take Smith.

middle of the game:
You generaly have buy the Wriggle's lantern so you can kill minion faster for make cash and experiance. You continue to put box into brush and you can begin to atack enemie alone by the back like an assassin. Is the better time for you for make kill so gogogo and have fun!

end of the game:
stop using jack in the box exept for use it like ward.
atack with your team for destroy/protect nexus.
Caution for ganking! if they are more than 2vs1 run quick!

Strategies

DECEIVE: try to teleport in the back of your enemie for activate your passive.
for escape try to teleport behind enemie and go in grass.

JACK IN THE BOX

try to put 3-4 box in the same brush for massive fear/dommage in same time
in one vs one put a box behind your enemie can make him return and allow you to use your passive.

TWO-SHIV POISON

Try to doesn't use your active for kill neutral monster because it gonna kill your Two-Shiv Poison passive

HALLUCINATE

use Alt-click for move your double
you can send it on a enemie with less healt if the enemies kill it he gonna lost some healt.
you can send it to your turret normaly enemies gonan fallow it so you can escape after.
you can kill turret faster!

Don't forget: its more easy to kill magician or range (with less health) before tanks

My favorite target:
Ashe, Caitlyn, Ryze, Annie, Veigar etc.
