Eh, even with oracle, shaco can still rack up the damage on others and still escape with ease. ghost and decieve work great together, even if you can be seen. Using hallucinate with it might not affect smarter players, but still be a slight annoyance which might just be enough to escape with.
Also today I had an epic game with shaco, lume was there, 1 triple kill and I ended up backdooring both turrets and their nexus to win. went 15/4/10.
I bet you guys didn't know that the best Shaco build right now is all sunfire capes. Suntank shaco gets double the Sunfire AOE, since the ones from his clone stack, deceives around you, and then roasts you to death.
