This comp looks to use chrono and valkyrie to buff up Kayle to carry the team. 4 Chrono can be a good mid game synergy, but late game there are better units to run that make use of better synergies.
If you can grab an early Kayle, or find lots of blademaster and chrono units in the early game.
Any unit you find upgraded will suffice in the early game. These units are ideal as they transition nicely, but any units will suffice.
Ideally you will find Kayle early and start building around her, but Xayah can hold her items before you find her. Irelia can also be a nice pickup to strengthen your comp before you find Kayle.
