This comp focuses on three different strong carries. Fiora and Orianna are your main damage carries, while Lissandra will be there for a bit of damage but mostly utility. The items in this comp are also very flexible, so you shouldn't worry too much about starting items.
Go for this comp if you have good items for Fiora. The other items are easy to build into any comp, so decide based on if you have good Fiora items or not.
Level up to 4 early if you want to start a win streak. Level up to 5 to try and continue the streak.
If you're weak in the early game, you can opt to save gold and lose streak instead.
At Round 3-2, level up to 6 regardless of your start. Put together the strongest team you can.
At Round 1, level up to 7. Roll down to stabilize your comp if you are weak. Afterward save up to hit level 8 and complete your comp.
For the early game, the only low cost unit that is a must to pick up is Blitzcrank. You can pair him with other Bodyguards and Scrap units for a strong early board.
Lissandra is the only 3 cost upgrade for this comp, so look for her along with other Scholars like Heimerdinger or Zyra. You can run a lot of other units like Arcanists to hold Orianna items or an AD carry to hold Fiora items.
Items like Chalice, Guardian Angel, and Morellonomicon are all strong items that can easily fit on any team comp. When looking for Fiora items, good scaling items like Titan's Resolve or Giant Slayer are solid, and other good options include: Bloodthirster, Hand of Justice, and more.
