Moose (M): Moves like a Grasshopper, but deflects 45° either way on passing over the hurdle. The arrival square is adjacent to the hurdle. (Grasshopper (G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.)
Circe: Captured units (not Ks) reappear on their game-array squares, of the same colour in the case of pieces, on the file of capture in the case of pawns, and on the promotion square of the file of capture in the case of fairy pieces. If the rebirth square is occupied the capture is normal.

I especially like the mates by nMb8 and nZd8, and how those same pieces must not give self-check on the same squares after Circe rebirths.
This can be done twinless, if you use a pion complet:
W: Ka4 Pb3 Pc5 Pc6 Mh8
B: Ka6 Bg1 Pa7 Pf5 Pg6 Za2
N: Ph2 PCc7

(C+ WinChloe)
The play is very series-like indeed (more direct series for that matter), but introducing a new type of fairy piece?
If you change the PC to a normal pawn, and use the same twinning mechanism as the original composition, this is C+ too.
W: Ka4 Pb3 Pc5 Pc6 Mh8
B: Ka6 Pa7 Pf5 Pg6 Za2
N: Ph2 Pb7
ser-h#3 Circe
(b) b7->c7
(c) b7->d7
In the light of current discussion, I can propose the following version.
White : Ka4 Pc6c5
Black : Ka6 Sd5a2 Pa7g6b3h3 MOf5 Zd8
Neutral : Pc7h2
b) Zd8>b8, 2.1…
Why a knight on a2 and not a pawn?
Personally, I don’t like the unbalanced twinning (unequal number of solutions).
Still imbalanced in another way, but…
White : Ka4 Pc6c5
Black : Ka6 Sd5a2 Pa7f5b3h3 MOg6 Zd8
Neutral : Pc7h2
b) d8->b8
c) d8->f6
And “classic” twins of type
b) npc7->b7
c) nPc7->d7
are also possible.
