Ours states that "The crew with highest Soulstone cost within each table Quarter controls it." So the argument is that the Tanuki counts as two models but still only have a Soulstone value of 5. Its not two Tanuki models, it's one Tanuki counting as 2 models.
If tanuki use their ability to pass and count as 2 models for the purposes of schemes and strategies, does it count as 10 ss in one corner for Ours? I can see arguments for both for and against it, just looking for an official ruling
