#2 transmuted Kings(6+6)
transmuted Kings : When a king is in check, it adopts the movement of the piece that threatens it for the duration of the check.
Here, if there were no Bh1, c5-c6 would mate, with the King adopting the pawn's march.

h#2 Anticirce(4+12)
🨢a3: Nightrider🨷a4: Camel🨍b3: Giraffe
Anticirce : the capturing unit returns to its native square, which must be free
A special case is if the capture and rebirth squares are identical.
Two types of anti-circe: Calvet - authorised and Cheylan - prohibited.
Another special case concerns fairy pieces.
As they are necessarily the result of a promotion, they are reborn on the promotion square of the capture column.
Nightrider : extended Knight
Camel : bouncer (1,3)
Giraffe : bouncer (1,4)
