Do I understand the rules correctly in that all center cards are replaced when defeated/bought?
So I can if I have good power cards spend some runes on replacing cheap cards in order to hope something stronger with a better reward will come up to replace them cards, or is the turn played with the cards at the center and then replaced when your turn finishes?
The rules as I read them seems to suggest that they are replaced when fought/bought but that made the game feel very strange. This might simply be a feeling based on playing a lot of Dominion lately with its restrictions.
