So by the sizes of the decks in the core set (30 for each sphere) it seems that the intention is for you to try out each sphere on its own againts the starting scenario and then build a 50, split-sphere tournament deck. Atleast thats the only reason that I can find for you to need "a second core set for up to 4 players" (apart fromthe fact that the other two players will need pen and paper to keep track of their threat. GOD FORBID!)
I was wondering if I was the only one who decided to just run 30 decks (even when mixing spheres) atleast untill more cards are added to the pool. It seems really convenient to stick at 30 untill there are more genuinely usefull cards in the pool (especially in single player where a good handfull of the cards dont really work) I did the same with Game of Thrones, I stcuk with 40 and then moved up to 50 and then to tournament 60 as I bought more cards.
I was just wondering if Im the only one who thought this about the core set, would it be "cheating" in some sense to just stick with 4 decks of 30? It just seems more economical to me (both draw wise and money wise) to do so, do other people who run 50 card decks find their draw is cluttered with useless cards in solo play?
