Chess.com variants has the ability to create custom board dimensions like 10x8 but currently it doesn't have any piece that can summon another piece. I don't think other apps like Chesscraft could do too but I could be wrong.
The only way you could allow summoning of pieces is with Crazyhouse option.
Multiverse Chess has a lot of spawners similar to the piece you described, and also Custom Boards.
Is it possible to create a copycat? The queen is replaced with the copycat. The copycat can imitate the piece that was played the most recent by your opponent. If the other person played their copycat, yours will function just like the queen. The copycat maintains the ability of the copied piece, until your opponent plays their next move. And lastly, if the copycat copies the king, it cannot be checked and can block checks to the real king.
No, that is not possible on chess.con
What about guard.It moves 2 rows in every direction and it has a shield witch saves him from attack but only once.The shield can be gifted to other cards expect king.Or miner which can move under other pieces but max 4 rows and eliminates the same.Miner can't go under guard and knight can't jump over guard.
Thank you
It’s my first time creating a chess variant and I’m trying to create a new piece called the war king. To get it you need to capture an opponents Knight, and then use up a turn to convert your King to a war King. Does anyone know how to create a new piece?
I want to create a 10 x 8 board with a new piece next to each tower that has the power to summon pawns on the next diagonal square (or on the next square ahead), but can only move once to the side. I wanted the site to have a structure for creating pieces
Can’t imagine why anyone would play that.

For chesscraft, this is possible using the "make piece" button.

I knew that
piece creator when 
(i hope that it's extremely good with lots of cool features [an example could be like you could set up the movement of the piece, similar to chess craft, but the chessboard is masive, like 30x30 or something])
the image below has an example of a custom night that can ONLY MOVE in 2 sides, and in the other sides, ONLY ATTACK
(don't ask why i inserted an example of a custon piece, i just felt like it)

The nice thing about such pieces is that they are not overpowered, rather subtile and we have to get used to them.
Does anybody here know how to actually create a chess piece on chess.com?
