Say I've culled most of my dice. I have 3 portals, 3 basic quiddity dice and 1 assistant. I draw all but 2 portals from my bag, and the one portal die I do draw I roll a "2 portal". I draw two portals from my bag and roll them, and put the portal die I just used into my Used pile. Both portal dice come up "2 portal" I set one in my used pile, and refill my bag from my used pile.
I imagine you can see where this is going. Is it okay to tournament-short-cut 2 of the three portal dice to "1 quiddity" and then roll the last one? Or can dice rolled this turn not go back in the bag?
