Standard Noob Question: What to buy? in KeyForge Posted September 27, 2020 · Edited September 27, 2020 by Zalco My overall ranking of how much I like each set is: 1) The Call of the Archons - The original is by far my favorite. 2) Mass Mutation - The deck are probably not as strong as Worlds Collide on average but I think it's better designed. 3) Worlds Collide - Some strong decks, but a little boring compared to the other sets. And one house is (Brobnar) is just very badly designed, maybe the design was done by a intern or something. 4) Age of Ascension - Just avoid that one.
