Introduction: I really liked the brawlers+marauders Yi comp in the previous set and I tried to figure out a similar comp in this set so I cooked this variation that nobody plays. In the Aphelios Vanguards variation you only play 2 ravagers, but with an early Kha you can get to 4 Ravagers 4 Vanguards,3 Riftbeasts (Brambleback Mark), 2 Lunar, 2 Rapidfire. Kha'Zix is the main priority of playing this comp, you need him early so he can stack the ravager and the rapidfire traits.
Items: Brambleback: Qss, Edge of Night +1( GS, Sterak's) or Artifact (Seeker's, Hellfire Hatchet, Titanic Hydra, Infinity Force)
Don't get range extender on him or Mittens( Brambleback's slow movement and big model makes him wrap around enemy frontline sometimes and he gets to backline, Mittens would deny that by making him go supersonic)
Aphelios holds the utility: Last Whisper, Red Buff +1 (IE, DB, GS, Guinsoo's) or Flickerblades
Red Buff is not necessary since BB's autos burn the target but it's a good item on Aph.
Sentinel: Vow's/Adaptive Helm/Gargoyle/Warmog's, artifact Forbidden Idol
For Sentinel's itemization it's whatever you get, as many Vow's the better but I do like Gargoyle on him since I solo frontline him.
Leftovers: Tank items to Taric or Hecarim, Thieves Gloves onto the other Ravagers, AP items onto Kha/Diana ( they can be item holders for you lvl 9 Alune/Lux)
Champions: You can play Elise/Rakan till you get Taric. Your lvl 9 is Alune or Lux depending of what you get. Alune is better I am pretty sure if you also get to Spellweaver Kha, then lvl 10 Lunar Lux if the game gets you there.
Stage 2 and 3 game plan: Play around ravagers+upgraded frontline, early kha, prioritize qss and eon for BB + shred.
Augments: At least one combat and one item based + 1 econ. If rich in gold and HP from wisps/streak etc. go for 2x combat +1 item / 2x item +1 combat.
Consumable Stats from Wisps: All the consumables from wisps go onto Brambleback, only mana regen goes on Sentinel.
Games: Tried it in my last games(298 LP) and had an AVP of like 2.85 (1, 4 , 2 , 5 , 2, 5 , 1).
The 4th and the 2x 5ths were with late Kha'Zix ( only got to Ravager ) but still pretty solid results.
I would not recommend playing it without kha getting ravager and rapidfire, also solo frontline your strongest tank in the early game and place kha near your strong ravager so he gets takedowns and since you are not building any AP items he can hold guinsoo/red buff/eon/qss. One of the other problems in this comp is also Sentinel, he is super contested, till you get to 2 star Sentinel itemize 2 star Hecarim. You can also do the 4-1 rolldown before anyone else if you have good econ so you have better chances of finding it.
