As it is with progressive chess, this games mechanic seems a perfect foil for a conversion based game.
Most conventional conversion based variants use a drop in rule for piece reintroduction, which I would consider too cheap, as it nominally gives all pieces full access to the board as a first turn. It also arguably ruins the flow of a game.
Reverse circe would solve this problem nicely.
