Arknights Welfare FC-EX-6 Clear, Challenge Mode

What the Firelight Casts level FC-EX-6, Life Anew, Challenge Mode, cleared using only Welfare operators.
I use lots of healers. Otherwise, Vigil and Wolfpack manage all the enemies coming for the left gate. On the right, I have Puzzle for DP, Tachanka for block and physical damage, Astgenne for arts damage, and Czerny for block and arts damage. Then, I either have Jieyun facing right, to get to the enemies as they come out of the right-most gates, or I have Insider adding damage to the enemies Czerny is blocking. I am happy with it.
Welfare operators are as defined at:

Comments and advice are always appreciated.
