Riven & Caitlyn

We are trying to get through the early game, preferably using Yasuo, we put items on it that we will then move to level 7, we want to roll deeper to get Riven to get Headliner, then we go back to 50 economy and slow roll for it on level 3, and we can also roll Mordekaiser on level 3 (but it's not is required) at the end we are left with lvl 8 and Caitlyn for two as a second carry or immediately lvl 9 and a legend, maybe Yorick or Illaoi
