Magician's Death Match
is a Chess variant designed by BattleChess on chess.com.
It featurers five new piece types next to a regular FIDE set,
none of which are initially present on the board.
They cannot all be present at the same time;
basically there is just one replacement piece, the Magician, which starts in the hand,
and can be used as a substitute for one of the Bishops:
once during the game, instead of a normal move, the player can swap his Bishop for a Magician.
The other new piece types are promoted forms of the Magician.
The Magician is a divergent piece, i.e. its capture moves are not the same as its non-capture moves.
(Compare the Pawn.)
The basic move, with which it can both capture and non-capture, is that of a Bishop limited to only moving two squares.
Such a piece in itself would already be worth as much as a Knight,
but the Magician has a few extras:
it can also capture like a Rook, upto a distance of two squares.
And in both the diagonal and orthogonal directions it can make its captures (but not its non-captures) as a direct jump,
not blockable by what is on the intervening square.
That makes it slightly stronger than a Rook.
The Magician promotes when a friendly Pawn crosses into the 6th rank.
To what it promotes is determined by what the opponent's most powerful piece is,
where Q > R > B > N.
If the opponent only has Pawns, the Magician cannot promote.
In case of Q the Magician promotes to Prime Minister, for R to Chancellor, for B to Archbishop and for N to High Priestess.
These pieces all share the moves of the latter,
which are those of a Queen limited to two steps.
In addition they can all capture (but not non-capture) as a Knight, or with a direct jump to the second square in any direction.
That describes the moves of the High Priestess (which is worth nealy as much as Queen).
The A, C and PM, however, also have the normal moves (capture + non-capture) of a Bishop, Rook or Queen, respectively,
and are significantly stronger.
Pawns themselves can promote when they reach last rank, to Knight, Bishop, Rook, or Queen.
If there is no friendly Magician (or promoted version of it) on the board,
they can also promote to one, or one of its relatives.
What exactly it can promote to depends on the highest opponent piece, in the same way as when a Magician promotes.
Pawn double push, e.p. capture and castling are as in orthodox Chess.
