Early units (1-5):
*MORDEKAISER*
*LUCIAN*
Vayne
Fiora
Garen
Darius
Warwick
Nidalee
Graves
Tristana
Kassadin
Lissandra

Basically use any 2 star units but prioritize 2-set bonus.
(Knights/Wild, Knights/Gunslinger, Gunslinger/Wild, Nobles or Pirates)

Lissandra holds ASol items, Tristana/Nidalee holds Jinx items, or Lucian/Nidalee holds Kaisa items.
Garen/Darius can hold tank items or Morellos

Mid(5-8):
*LEONA*
*JINX*
*ASOL*
Sejuani
Kindred
Braum
Poppy
ChoGath
Vi
Pantheon/Kayle/Kaisa/Karthus

Mid depends on what you got early. Just strengthen whatever set bonuses you went for.
(4-Knights/Gunslinger, Knight/Brawler/Gunslinger, 4-Knight/Wild w/ Lucian)

Braum or Poppy can hold items for Pantheon.

If you were holding onto Nobles early and you see Kayle at 7-8, then 6-Noble/Jinx.
If you got a Spatula at any point, then you should look for 4-Knight/Guardian/Dragon/Sorcerer.

Late: (8-9)
*PANTHEON*
Kaisa
Kayle
Karthus
