Thank you for sharing this case study.
From my point of view: Self line is filled by wu month, so it is not empty. It changes to Wei Active with return combination with its original line. This active wei is "pulled" and supported by the month which suggests to me that wei is able to come out of the void as well. This Wei damages L1 Zi Parent Other. At the same time the Wu Offspring Self clashed and insults the "battered" Other line (the tiger underlines this idea), who receives no support.
I would therefore say that Self won (Team A).
