/it was a joke, I would think the double snowball items would be obvious enough
Pffthaha, my usual build actually would be:

Well, that's how it ends, usually. I would by a
early on when necessary, and
(although I would often sell it without upgrading by late game) to help with movement if I deem necessary.
I also have a more "Cowsep"/melee carry play style instead of a traditional assassin. What I do is attack the closest thing to me to charge my Alpha Strike as fast as possible, so that I can dodge enemy CC as they come at me with Alpha Strike. Because of this, I need to optimize for tank busting, as my play stye will often pit me against tanks.
Also, I don't like Shiv on Yi (specifically melee carry Yi, I appreciate SS on Assassin Yi). There's no kill like overkill, and Master Yi is a late game champ (PD>SS in the late game).
