League of Legends, Farm then Sweep the Enemy

Champion, Caitlyn
Plan, Farm minions ALL GAME then use that massive Gold and Level advantage to sweep the enemy team.
Items, Infinity Edge to make Caitlyn Passive twice as strong, Percent Armor Penetration Crit to make my damage harder to reduce, Collector to make my damage harder to reduce, Essence Reaver because it was the biggest AD crit item I could think of.
Boots depend on what you want.
Last item whatever you want, I recommend raw AD because you already have 100 crit and more is useless and the armor penetration you have combined with the ad stats would make lethality items which have lower ad less valuable for the armor penetration they which is small in comparison to the sheer boost to your passive from the raw ad you build with Ravenous Hydra as an example.
