Question you may know the answer to. If you get a card or roll are you disallowed from lotting on it on future runs if you used it? They do this for minions all the time, and scrolls occasionally, and when the Void Arc dropped only one card you couldn't lot on it if you had it. Did they do the same here?

You can roll on it if you don' have it in the inventory. Unlike with not sellable minions (you can get sellable minions multiple times), you can still get cards you already have and sell them for MGP.
