And after read this, I want both Daisetsu and Sotori's cards :D, lol
Anyway, in a possible civil war scenario, who will stand for Sotori? So many people in my opinion...
For example, if Unicorn will follow Daisetsu, you can easily have Lion going on the other side (maybe also naming a new champion over Tutori?). Maybe also Phoenix will support Sotori, for stay on tradition (first heir).
Crab and Mantis could move for power or "money": Crab need more jade, Mantis could ask for be a great clan.
To be honest, except for Unicorn and Scorpion, who will, in my opinion, support Daisetsu; all other clans are on 50% and they will choose what they think is more profitable in their opinion (power and influence)
