"My" variant

Ok, so this is a variant of chess I've sorta-ish come up this. In truth, it's a variant of a variant. The original variant is called Tencubed by David Paulowich. Look it up if you want. "My" variant is played on a 10x10 board. No castling allowed, pawns move and promote exactly like in normal chess.

Onto the pieces:

Champion, from Daniel C. MacDonald's Omega Chess. Slides n' captures one square orthogonally in every direction or jumps n' captures exactly two squares orthogonally and diagonally. 

Wizard, also from Omega Chess. Slides and captures one square diagonally in each direction or jumps and captures in a (3,1)/(1,3) pattern in every direction. 

Duke, a piece thought out by Sean/SeanH7532 (in chess.com and elsewhere). Now this one is an interesting piece. It slides like a queen, but it can only capture like a king, that is to say, one square orthogonally or diagonally. I'm using the Guard from Bulldog chess because i like the way it looks (credits to whoever created its art by the way).

The goal is the same: checkmate the enemy king. Stalemates work just like in normal chess (though this is subject to change).

Further credit and thanks to @CouchTomato, who brainstormed with me, and the creator of the Musketeer Chess variant and the board painting tool https://musketeerchess.net/tools/boardpainter/ .

The reason this variant exists is because, although i am a bad player, i often felt like normal chess suffocated me with it's not-that-big board and limited number of pieces. After looking into variants for a long time, I decided I knew what the perfect chess variant for me would be. It would have either all or almost all pieces from normal chess along with a few more fairy pieces along with a slightly bigger board. So what's wrong with TenCubed? Well, TenCubed has two pieces I've grown to dislike; the Archbishop (bishop+knight) and the Marshall (rook+knight).

While those two pieces seem the logical and natural conclusion one comes to if one wants to make up a new chess piece in his head, the issue with those two is that they are simply too powerful. In a 10x10 or 10x8 board, they make the bishops and knights seem almost insignificant in comparison. 

Thus I decided that the fairy pieces that my perfect chess variant would need are middle-tier pieces with not-too-complex movement patterns. Middle-tier to me are pieces whose strength is somewhere between being slightly more powerful than the knight or bishop (~3-3.5 pawns worth) to being somewhat more powerful than the rook (~5-6 pawns worth) but not nearly as powerful as the queen (~9 pawns worth). The Champion and the Wizard seem to be on this level and the Duke's strength is still unknown, but I doubt it will be significantly more powerful or weaker than the two aforementioned pieces.

Final notes: The original TenCubed chess is called such because it is played on a 10x10 board and there are 10 kinds of pieces on the board. Seeing how I removed the Archbishop and Marshall and replaced them with two Dukes, there are only 9 pieces on the board, so the addition of a new piece seems to be in place. Three options present themselves to me:

1- replace one Duke with a Centaur/Paladin (knight+king movement)

2- make the normal knights promotable to a Paladin should they reach the opponent's last file or somesuch

3- Add Omega Chess' Joker/Fool, who is initially outside the board, gets put in it during the game and copies whatever movement the opponent's last moved piece had

But this is a thought for another time

DAMN! That's fantastic!!!
