Master Yi strategy with 7 Demacia (I earned +350 LP with this strategy)

The final comp at lvl 8 is simply 7 Demacia + juggernaut (preferably Aatrox but Nasus is a good unit as well). You want your Demacia Elites to be: Garen, Lux, Sona and Jarvan. These are the most impactful units and they are unleashed when they have a radiant item.

About positioning it's very straightforward, just make sure all your units get the Demacia armor and MR buffs. If you have Aatrox, put him next to Garen so he can receive the Darkin buff whenever Aatrox dies.

At lvl 9, you can add Heimer to have shred and anti heal but you can also decide to remove Poppy and Galio to add more 5 cost units.

This comp is pretty straightforward and easy to play but it's important to know when to push and when to roll.

Stage 2

• Prioritize Demacia units (Kayle, Poppy, Galio) and play units that can hold Garen / Lux items well. Samira is an excellent item holder for both, for instance (she can have blue buff or AD items)
• Make sure to pick Garen at the stage 2 carousel, regardless of his item, if he appears. it's more important to have Garen early than stacking the perfect items
• Always pick Pumping Up! augment from Master Yi, except for the augments I'll show below
• Either play strong board or weak board based on your units (basically play the early game normally, you don't need to open fort to play Garen)

Stage 3

• Push lvl 6 at stage 3-2. If you are missing 1 Demacia to have 5 Demacia, you can roll a little bit
• It's fine if you still don't have Garen, but you should expect to lose fights at this point
• If you have a lot of gold thanks to a huge loss streak OR thanks to an econ portal like Scuttle Puddle, push lvl 7 at stage 3-5 and roll for 7 Demacia
• If not, then wait until stage 4 to push lvl 7

Stage 4

• You are lvl 7, and you NEED to have 7 Demacia on board. Most low-cost Demacia needs to be 2 stars and only Jarvan and Luyx can be at 1 star at this moment
• Roll as deep as you need to achieve the 7 Demacia board. If you achieve it, you should win most fights.
• Pick Gotta Go Fast at stage 4-2 unless it's a prismatic augment and you have something better
• After rolling down, get back your econ at 50 gold thanks to your winstreak

Stage 5

• This is the moment when you'll decide to either reroll Garen 3 or push 8 and aim for a top 4.
• If you are uncontested and already have a couple of Garen on your bench, you can reroll Garen 3
• If you are contested or you low roll the Garen, push lvl 8 and find Jarvan 2, Lux 2 and a good Juggernaut like Nasus or Aatrox.

During the early game you mostly want to play around Demacia and good item holder units like Samira or Warwick.

At lvl 7 it's capital to have 7 Demacia with all the low-cost units at 2 stars. This gives you a huge power spike and you should be able to win most fights.

Since the strategy requires Master, playing this comp with this Legend only makes sense. However, Not all Master Yi augments are great. Try to avoid Battle Ready (stage 3 augment) or the Prismatic Gotta Go Fast (stage 4) because they are overall not giving enough stats.

Even if Master Yi has good augments, there are augments that are simply better to play Demacia so do not hesitate to roll the other augments and pick any from the S tier to have easier games.

One good thing with Demacia is that you are not punished if you don't have the BiS (best in slot). Meaning that as long as you have sustain on Garen (with BT) and two items on Lux, they will still slap hard!
