I'm coming around to the idea of using APR, AMR, Retort, and B O X myself.
Because this is showing off not entirely our skills, because our skills are mediocre regardless to the judges. It's showing how far we've come as a crafter since arriving here.
More importantly, APR is simultaneously an Archer and Defender charm, and with Dance serving as cover, it's very good at handling surprises. Widow's Ward technically isn't ours to use (Even if the owner's offered it to us). It was also explicitly called out as not being the flashiest thing we had, and we need to put on a show. APR is extremely flashy along with its flexibility--and I point out that it was considered very impressive that Kong Zhi could combine Light and Water Anam the way he did by Shouxi--who while he's in a different line is also a crafter. This likely matters.
Aesthetically? It's a coherent build. Jai Fa has one hand and arm with APR and AMR equipped, her off-hand gets to use Retort as a hold-out and a defense breaker, and she gets to lean on B O X to seize the advantage. It's a very coherent, very strong build that shouldn't cause much mutual interference.
