Madred and Last whisper are here for tank. They are last 'cause that's useless for me to rush them in early. Tank are invincible in end game so you need these things in end game. Sure you have to rush madred if all team in front is tank or AP-tank, just switch with infinity edge.

If you rush them instead team has just one tank, you will be useless in early. Shaco has been so nerf that madred is not suffisant to kill carrys, your primary job.

I made this build for Shaco's players who are boring to be useless in early and killer in end game. With this, you are a killer in early and a killer in end game, you juste have to don't stay near tanks in early.

If you don't understand 'cause of my english, say it :3

Thank for your coment.

This looks like a true killer build. But... Isn't it better to go for some arp runes too? I mean, killing a tank is almost impossible except if you have you Last Whisperer or such.
