İ listed the items,, if you ask me why i choose guardian angel in the middle of the game, this is because trinity force and youmuu's ghostblade will be enough for killing someone quickly. and why guardian angel? Shaco character can be killed easily if you dont use deceive and run away,, But lets think about your deceive skll in cooldown.. (Actually when we need deceive skill , it usually in cooldown...). So we are going to die. But if we have guardian angel first of all we ll gain much durability and we wll stay alive much longer,, but lets say we died .. we will return in few sec. AND THİS FEW SEC GİVİNG US A CHANCE FOR ENDİNG OF DECİEVE SKILL'S COOLDOWN . So we can use decieve to escave area..

Why am i choosing all att speed rune?
Trust me the best choise on almost all fightter, Think about begining with 0.985 att speed, if you take armor pen. rune its not a bad choise too, but att speed runes is awsome choise. Your enemy's att speed will be 0.625 at 1 lwl ,, its mean you will double strike while your enemy's attacking first strike..

Start with ruby and open jack in the box.. go to jungle immediately and put 5 boxes on blue buffs and put sixth box while you are attacking blue golem. Dont take damage from buff golem.. then go to your line .. And always look at all your enemy champs healt for getting easy kills. With this items and runes shaco can get all one on ones :

THis Exhaust and İgnite spells will be make you op in game. Trust Me!! Try to dont use both of these spells in the same time. But if your enemy had feeded you can use both
