Proofgame in 7.0 (Circe assassin)

Circe Clone: A captured unit changes into a piece of the same kind as 
the capturing unit (without changing colour) and is then reborn on the 
game array square of the new piece, according to normal Circe rules. If 
the rebirth square is occupied, the captured unit vanishes. When a 
promotion by capture occurs, the captured unit does not change into the 
promoted piece but into a pawn and is then reborn in the same way it 
would be reborn after any other pawn capture. In case the capturing unit 
is a king, normal circe applies.
Circe assassin: Like circe, but when the rebirth square is occupied, the 
occupant is 'assassinated' (replaced) by the captured unit.

PS: In the definition of Circe assassin, it's not 100% clear what 
happens when a piece is captured on its game array square. My 
interpretation is that the capturing unit disappears. I.e. in the 
diagram position of the 3rd prize, if it were black to play, after 
e3xd2, the reborn white pawn would assassinate the black one on d2.
