For this abyss specifically, I think taking advantage of the blessing and using anemo on both sides is good. You’ll also probably want a geo unit on the second half as well as a team which is strong against both single-target bosses and AOE situations. Here’s a suggestion:

First half: Kazuha national (Kazuha, Bennett, Xiangling, Xingqiu)

Just try to stack enough ER on all these characters and your rotations will be easy. Survivability is fine with Bennett, Bennett and Kazuha on VV will buff the other two.

Second half: Triple archon (Raiden, Zhongli, Venti, Traveler)

As always, make sure you have sufficient recharge on Raiden and Traveler. You might want to level up your Traveler because this team doesn’t have a healer, so you can either tank it out or dodge as much as possible in the last chamber. Alternatively you can use Kokomi instead of Zhongli, although you might be a bit slower in breaking the wolflord skulls in Chamber 2. Also make sure to use Raiden E > Venti Q > Traveler EQ so that you can efficiently swirl Electro—if you apply Dendro before swirling it will react with the Electro and swirling might be difficult.

Hope this helps, feel free to clarify or ask more :)
