Congrats on the pull, I'm quite jealous of you. I don't know how to read kanji, but I've found two A1 clear videos. I don't think they count as speed clears though...
From what I've seen, you need to have a few subs with high RCV and orb changers to combo with. Wukong, Revo Venus, Revo Amaterasu, Apocalypse, Revo Apollo, Alcyone, and Ana Valk would work. Basically any light God/Machine card should do the trick as long as you can shore up the RCV weakness.

Another team template
I played around with a few team ideas. The A1 Yomidra speed farm works pretty much identically here with enough low end damage to play around sopdet and have an inherit for Parvati. I also tried a couple more standard builds. Whenever I have a bindable lead with defensive components tied to the leaderskill I feel compelled to have a hard bind clear. Three ideas bouncing around:
Team 1: Never ending skyfall
Wescha
Revo Apollo
Allura
L/B Lmeta (Awoken Nene)
Super Wukong
Wescha
The idea here is you can have unlimited light skyfall at the cost of hearts. Wukong is there for emergency heartmaking and Lmeta is for bindclear and a combo board with Wukong. Works fine but RCV is still on the low end and move time is rough for combo shields. The maniac badge for either fixes the problem well enough for me so it's more of a which one is more applicable to a dungeon. Arena I'd probably use the RCV badge and let skyfall save me if I screw up.
Team 2: Guard Break
Wescha
Allura
Revo Indra
Alcyone (or L/B Apollo)
Revo Sakuya
Wescha
Not sure how useful guard break is on a Wescha team but I thought I'd put it together. The advantages here are any activation + guard break will sweep a high defense floor, There's enough move time to make the rainbow + 5 match, RCV isn't much worse than the other options. Downside is so many heart breakers, Wescha's damage is probably good enough for any defense check barring the 3p Arena Metatrons
Team 3: Jack of all trades
Wescha (Saria)
L/B Lmeta (Awoken Nene)
Revo Indra (Indra)
Super Wukong (Super Wukong)
Revo Venus (Lakechi)
Wescha
This team can handle almost anything. RCV is enough to not require the badge so I can run TE. The only thing I'd like is a delay and a fujin-like. I can use an off color inherit I guess but the light delay options are real sad. 5 of 7 inheritable delays are collab only, two of those 5 are the same monster just the uevo'd form. The only perpetually available inheritable delays are Light Wee Jas and Sagirinokami. Sagirinokami is nice for the team because it delays and enhances light orbs. Revo Venus seems like the best home for a fujin/Hiko.
