Revenge Chess

Actual tutorial coming later, so here's the basic gist:

• Piece movement is the same as in chess, including castling, en passant, and promotion
• Whenever a piece captures another, it adds it to its list of captures
• Whenever a piece gets captured, all pieces in its list of captures are returned to the board in their starting locations
• If another piece is in the way of a respawn, then it gets captured by the respawning piece, even if they're the same color!
• Since there's situations where a king can be captured and immediately respawn (can you figure out how?) there is no check
• Various effects of there being no check/checkmate include: castling can be done through danger, pawns can promote to kings, the win condition is to leave your opponent with no kings left
