About This Team Comp
1) Vertical Duelist: Give early Duelist Emblem to Diana so you can reach 6 Duelist power spike early and have option for 8 Duelist chase trait in late game or cap out your board with Sages, Storyweavers or Legendaries.
2) Porcelain Volibear (Cocaine Bear): Needs 2 Porcelain Emblem to reach 6 Porcelain Chase trait. Volibear is the best user for the Porcelain Emblem and becomes unstoppable in late game.
3) Fine Vintage Duelists: You want to open with Fine Vintage Augment and collect multiple Zeke and Locket, since you position everyone in first row anyway. Can also add Banshee, Aegis or Zephyr to support your team further.
The core concept for all versions is usually based around having a strong early mid game and pushing Level 7 in early Stage 4. You want to slow roll for Tristana*3 and Volibear*3 and push towards Level 8/9 once you have them.
There are a lot of variations where you can run Inkshadows, Sages, Storyweaver or Dragonlords, which will depend on your units and Augments in the end. Sometimes you will be contested or might struggle to find your units, which can force you to utilize your mid game power spike to push for Level 8 and simply aim for a Top 4 placement.
Duelist Reroll
Team Carries
Recommended Augments
stage 2
If possible play 4 Duelist or a strong board in the early game, with early Volibear you can also run 3 Ink Shadow if your first Tattoo is useful
stage 3
Push for Level 6 in Stage 3-2. Depending on your Augments and items your priorities will change a lot. If you have a Duelist Emblem, give it to Diana and aim for 6 Duelist with 2 Sage. If you have a Porcelain Emblem give it to Volibear and aim towards 4 Duelist + 4 Porcelain. With no Emblem you can run 4 Duelist + 3 Ink Shadow or 2 Sage.
stage 4 - WITH DUELIST EMBLEM
Push for Level 7. If you have Duelist Emblem give it to Diana. Run 6 Duelist with 2 Dragonlord + 2 Sage. Slow roll with Level 7 for Volibear*3, Tristana*3 and Diana*3
stage 5+ - WITH DUELIST EMBLEM
Either run 8 Duelist, or Galio for 3 Storyweaver or Morgana/Wukong for more Sage.
Alternative with FINE VINTAGE
There is also a special version involving the Augment Fine Vintage. You can transform all of your items into Support items like Locket + Zeke and if you don't find them you can add Banshee, Zephyr or Aegis for additional Support. Itemize Tristana as your main carry and maximize the power of support items by placing your units in the frontline. Tristana can be in the front as well since he will jump to safety after her first cast.
Alternative Item Builds
You can skip Last Whisper if you find an early Irelia or run 3 Storyweaver with green Talisman Kayle. Irelia can also be itemized as carry, especially if struggle to find Tristana and want to push levels instead to transfer items. Volibear can be build as full tank if you have a strong Tristana.
Emblems
Volibear is best Porcelain user, if you find a second Emblem can give it to Tristana or Lee. Diana is the most common choice for Duelist Emblem but can also give it to Ashe if you're already running a Duelist/Porcelain setup.
I just tried my own version of cocaine bear. You want to get 6 duelists, 6 porcelane and 2 arcanist units. Basically my comp was
Voli(porce emblem,blood sword and titan)
Trist (recommended crit build items)
Irelia (porcelaine, gunblade and IE)
Ashe (Whatever I could use, ideally put a duelist emblem is godlike luck)
Lux
Lissandra
Yasuo
Amumu
Lee sin
Darius
You have no choice but to go for level 10 of course, but ideally if not you would have 6 porcelane with 4 duelists earlier. Level 9 if you have duelist emblem and 2 porce emblems
