Now, I'm actually reasonably sure that the intent behind Spirit Anchor is to give you new seishins, but the use of "place" confuses me.
Place moves things, sometimes it moves things that are not on the board onto the board, like killjoy and bete noir, but they're things you've paid the ss for already, they just don't deploy normally.
So the rule, for the uninitiated, reads like you can place one of the seishins you already have in B2B with Kirai, tell me why I'm wrong, please?
