And nowhere does it say you don't get to count his cost twice. Regardless of anyone's ruling, it's definitely ambiguous enough where I'm hopeful for an FAQ on it soon.
Until then, most events I've participated in rule Big Jake and Tanuki as counting their cost twice. So Nellie is my go-to when Ours comes up.
Models I like to take with Nellie in Ours:
Phiona because of her 1 AP action to place in base contact with an enemy engaged with a friendly model. That can be useful if you need to get her to a different table quarter. I always take Phiona with Nellie though.
Peacekeeper because its sturdy and can run pretty independently and has a high SS cost.
Big Jake for counting twice.
And Anna if I'm going up against Ten Thunders, Ressers, or Arcanists.
