So we get all exclusives in the stretch goals, easy.
But now we have the Spriggan hero that will be an exclusive mini, but the hero deck may come back for the druid. This means that the a Sprig card sleeves must be exclusive also, since they match the mini art.
So 20 more dollars.
What about the agents, are they exclusive?
They do not say so in the update so I would assume no.
