This team slow rolls at level 7 to build a Rebel core. Making Zed a Blademaster allows for extremely high damage output. This can also be played without Blademaster Zed, but is ideal with him.
This comp requires 3 star units, so try to have a good start with copies of your core units. The comps also requires a lot of Bows and a Spatula, so try to play this comp in Treasure Trove, or if you find an early Spatula.
As this is a slow roll comp, you want to spend Stage 2 saving up gold to hit 50 gold while mainly buying Blademaster units.
For this comp, you want to slow roll at level 7, using whatever units you can find up until that point. Don't be too greedy or you'll lose too much HP early.
After you hit your core of Zed, Master Yi, and Shen, start leveling to hit 8 to finish your comp. Ekko or Fizz are great for Infiltrator, while Lulu can also be put in for Celestial.
You can use Nocturne as an early item holder for Master Yi, and you can also add in Rebels at level 5. You can also use Rebels at level 4 if you don't find Zed early.
At level 6, you can hit 6 Blademasters if you find either a Riven or an Irelia. This will allow your team to powerspike assuming you have Blade of the Ruined King.
Considering the ideal items on Yi requires 3 bows and you also want a Spatula, this comp is quite item dependent. Make sure you are set to hit your ideal items or else you may not survive late game.
In the early game, you don't have to commit to a lose streak if you find lots of pairs. You can buy good cheap units to win streak, and then transition into this comp if you find lots of bows.
