This is my Shaco Build > or close enough to it. This build at late game will allow you to

.Solo Baron
.Decimate any tank
. 2-3 Hit squishy casters or carries
. Beat trynda =p even with his ultimate

I choose Flash and ignite because-
.Ignite is always good to help you rack up kills early or later game

.Flash lets you port in with your Q skill do massive damage with my awesome build, and get away safely

Alternatives would be
Teleport- for ganking, coordinate with allies to maximise your success.

Heal - I know many of you hate this skill but for tower diving it can be invaluable, prolonging the life of your Illusion / Yourself and your allies.

Rally - use this Q and ignite will give you a healthy damage boost.

Early game Shaco isn't exactly the best farmer but with this build you'll be getting decent money for doing nothing. Try to last hit minions there is nothing worse than criting a minion to like 1 hp and having your minion-kill stolen by an ally minion.

Pros -
Good steady income with minimal effort
You can Solo baron (you will need your ultimate)
Late game, nobody can tank you 1v1.
Easy kills
Your Ulty is like an extra team-mate pop this and the enemy team will run away
Cons -
Not very good farming but this wont matter when your destroying everyone.
