hey there are a couple pieces that was already added — for example dragon is called "amazon" in the fairy piece continuity that includes, hawk, elephant (elephant is rook combined with knight) so chancellor should be a elephant. archbishop— another name for a hawk (bishop-knight)
Piece list

The piece names aren't mainly based on fairy pieces. It's based on bulldog chess then musketeer chess. I have noted the alternate name amazon. Elephant and hawk are already used names so I'm not going to change the names of the chancellor and the archbishop nor note it as an acceptable alternative name.
Pawn (P) - 1 Point
Can only ever move forwards one square at a time and can capture one square in diagonal. Cannot be possessed by a spirit. Promotion rank at 6.
Pillar (Pi) - 1 Point
The upside-down version of the pawn. Moves downward instead of upward. Goes one square at a time and can capture diagonally. Promotion ranks at -6. Cannot be possessed by a spirit.
Knight (N) - 3 Points
Jumps by going two squares in one direction then one square in a perpendicular direction (creating an L). The move is legal as long as the square it ends up in is legal (not an uncapturable piece)
Guard (G) - 4 Points
Moves like a king. One square in every direction.
Hunter (Ht) - 4 Points
Moves like a king. Captures in a knight or squares exactly 2 moves in the rooks direction. It's a jump so blocking doesn't matter.
Bishop (B) - 5 Points
Moves diagonally infinitly if it isn't blocked.
King (K) - Free, but worth 5 Points.
Moves one square in any direction. Forced to have 1 king on the board. Your king is the source of your health regen, no king = no health generated. If you lose your king and choose not to respawn it yourself, then on the 3rd update it will automatically respawn where it died, or if that's occupied, then within 1 square of it, if all's occupied, then within 2 squares of it, etc..
Leopard (L) - 5 Points
Moves and captures like a knight or, one or two squares diagonally.
Zombie (Z) - 5 Points
Slides up to two squares in a rook's direction (cannot jump). The zombie can not capture pieces, but "scares" enemy pieces with fright instead. All enemy pieces within its attack range are frozen and cannot move. Pieces remain frozen until the zombie moves, is captured or blocked. Zombies will not freeze other zombies.
Spirit (S) - 5.5 Points
A spirit moves as a knight. It can 'capture' friendly pieces, which gain the movement of a knight in addition to it's other abilities (knights are not affected, but can be used for transportation. A 'possessed' piece can be captured like normal. It is transparent to friendly pieces. Spirits ARE capturable in this game to prevent use as shields. They do have the ability to exit pieces they're possessing. And cannot capture enemy pieces if they're alone. Pawns and pillars cannot be possessed by spirits.
Elephant (E) - 6 Points
Moves like a king but can also jump two squares in the directions a queen can go.
Hawk (H) - 6 Points
Can leap two or three squares in the directions a queen can go.
Unicorn (U) - 7 Points
Moves like a knight (1 in a direction then 2 in another) but also has an expended knight move (1 in a direction then 3 in another).
Witch (W) - 7 Points
The witch is transparent to friendly pieces, and she also makes all adjacent pieces (friend and foe) transparent to friendly pieces (but pieces are not transparent for the witch). The witch does not capture other pieces, but she can be captured. Although pieces are not transparent to the witch, she is very agile; she combines the movement of queen, knight, and can jump orthogonally and diagonally two squares. Transparency of a piece means that other pieces can move, attack, and capture right through the piece.
Rook (R) - 7 Points
Moves orthogonally (ie along rows and columns)
Spider (Sp) - 7 Points
Can move diagonally one or two squares. Can jump like a knight and exactly two squares to directions a rook moves.
Archbishop (Ab) - 9 Points
Moves like a bishop and a knight.
Dwarf (D) - 10 Points
Moves like a king. Must be attacked by 2 pieces opponent pieces to be captured, they do not have to be the same color. [add rule if nukes added]
Chancellor (C) / (Ch) - 11 Points
Moves like a knight and a rook.
Time Thief (Tt) - 12 Points
The Time Thief moves like a Queen, but does not have a normal capture. The Time Thief has a special move that is done in 2 steps.
Undo your opponents previous move (restore position to exactly the same as before, which might include putting back a captured piece).
Move your time thief (like a queen) and capture the piece that moved on your opponents previous turn.
The Time Thief may not undo a move if the Time Thief was captured or if it is unable to capture the piece that moved after undoing the move.
Note that this means the Time Thief must "see" the piece before it moved.
When capturing, does not rewind the entire board, rather it undoes the effects of the move caused by the piece captured.
Queen (Q) - 13 Points
Moves like a rook and a bishop.
Harpy (Hp) - 16 Points
A Harpy moves as a Queen + Knight. It may be captured, but it cannot capture enemy pieces. It captures one of its own pieces and drops it on the board. Pieces may be dropped on any unoccupied square, as in Bughouse and Crazyhouse. Can only drop pieces within it's own movement range. Pieces *tossed* by a harpy are NOT disabled a move. Harpies have up to 4 moves to toss the piece beneath them before they are crushed and converted into 50% health. Harpies cannot capture pawns, if they attempt to then the pawn will be instantly converted into 1 health.
Dragon (also called amazon) (Dr) - 17 Points
Moves like a queen and a knight
Angel (A) - 20 Points
The angel makes all friendly adjacent pieces immune from capture. The angel does not capture other pieces, but she can be captured. The angel combines the movement of queen, knight, and can jump orthogonally and diagonally two squares. The Angel makes friendly adjacent pieces immune, not only from capture, but also from all other side influences by other weird pieces. So she would also protect from the freezing abilities, and from the spells of the Witch. Angels do not provide immunity to other angels.
