Hi, newbie here...
When figures get defeated in battle, can they be summoned again in later rounds or are they out of the game? If you spend all of your 24 chaos cards, do you simply shuffle your discard pile to form a new chaos card deck? Or are the discarded chaos cards out of the game?
Figures can be recycled. Discards are reshuffled if you run out. Though it rarely happens that you can make it through a deck.
