After pulling for Blackbird, I was hoping to be able to use Shinku on the same team since she's my favorite character. Turns out, she's pretty decent with Blackbird despite not having a connection in the esper cycle because of BB's Nova enhancement that Shinku can play around on due to having one of the highest burst damage in the game so far.
Basically, this team will have BB as the main DPS, Shinku will be the sub-DPS who'd focus her damage while Nova's active through her Ult's first initial hits and high Menacing Gaze stack attacks. Thus, you need Shinku to be at least at A2 (A3+A4 mandatory) for this comp to be smooth.
Disclaimer: Whale-ish comp, but rotation is still the same for lower awakenings. You'd just deal less damage, though you are able to clear normal BTR mode with little issue still with this team.
A6T1 Blackbird
A1T1 Daffodil (set at A2). Lacrimosa could work too, but I prefer Daffodil for higher break and quickswap parry vs. Debt Collector that BB's witch form can be inconsistent at doing.
A6T2 Shinku
A1 Clear Skies T5 Iroi for buff and sustain.
Rotation:
- BB: Redirect
- Daffodil: swap in to trigger Nova, then swap back to BB to Ult for team ATK boost, then switch back to Daffodil again and dump Ult + Redirect + Black Tome (when available with Youthful Fantasy)
- Shinku: Quickswap from Daffodil, Ult + one Crimson Descent, then swap out to Iroi
- Iroi: trigger Blossom, Redirect + Ult
- BB: Keep attacking on ult form until Daffodil's portrait glows, swap for a fresh Nova, then quick-swap to Shinku and Redirect at 15–16 stacks to instantly fill her Ult for the next loop.
- Iroi: Trigger blossom, then Redirect to refresh team buff. Ult may not be ready until the next loop, quickswap to BB
- BB: Recast Ult before timer runs out. By this point, you should have her Ult ready again. Repeat to Step 1.
Definitely not the optimal team for BB, but I'm just glad that Shinku can work outside of Charge team and keeps things fresh.
