Fairy conditions:

- AntiCirce Cheylan: When capturing, the capturing piece is reborn on its game array square, the captured piece is removed. The rebirth square must be empty. A piece can't capture on its own rebirth square.

- Losing chess: Kings are non-royal. The goal of the game is to get rid of all pieces.

- Mirrorcirce: When captured, a piece is reborn like in Circe, but on the rebirth square of the opposite colur. (I.e. the white queen is reborn on d8, a black pawn is reborn on the 2nd line)
