This comp looks to slow roll to find 3 star units early game. Using Xayah 3 will carry the early game to hit level 8 to fit in 6 Blademasters.
Go for this comp if you find early copies of the core units and have a strong economy to hyper roll after Krugs. Make sure you also have good items for Xayah as she is the main carry and core of the build.
Stage 2
Before Terrabusters
As this is a hyper roll comp, you will want to make as much gold as possible without rolling or leveling at all during this stage.
Stage 3
Before Anchortails
During this stage, slow roll your gold above 50 to look for Xayah, Jarvan, and Fiora. Fiora is the least important, but Jarvan will be hard to hit 3 star. Xayah will be the most important to 3 star.
Stage 4
Before Arcraptors
At Round 2 you will be close to hitting level 6. If you are still missing Xayah 3 star, continue rolling before leveling up. After that, you can build your economy back up to 50 to slow roll for units like Shen and Rakan. Alternatively, you can rush level 8 after hitting Xayah 3 to complete your team.
Xayah will definitely carry early with any items, but will need ideal items in order to deal enough damage late game.
Since this comp only relies on one 1-cost unit, don't over roll after the Krugs as Xayah will be enough to carry the early game. Look to rebuild your economy and roll for higher cost units.
If you are extremely fortunate before Krugs and find 6-7 copies of Xayah or Jarvan, you can roll down to around 30 at 3-1 to try and hit an early 3 star.
