solution 1.cxd6ep+ Sxc3 2.d7 Lxg7#
Last move was not c4xd3 or e4xd3 (on a light square), because the missing white man is the dark-squared [Lc1], so it was d7-d5, legitimizing the ep key (2021-10-03)
A.Buchanan: Sound + lighter + W2 becomes sole viable tempo move (with 10 other White pieces able to move). (2021-10-04)

Judge Julia Vysotska (The Problemist, November 2018, p.510-513): "A pawn, seemingly destined to block its own king, suddenly leaves there to promote into three different hoppers, and to jump far away! A complete cycle of 2 promoted pieces (promotes and blocks, promotes and mates) and a blocked black hurdle. All promotions appear on the first moves, with nice anticipatory blocks of the hurdle by the black promoted piece, and mates by the white promoted piece. A pity that the BHb4 is needed only for BH promotion in two first solutions, while the NH and RH are in a superior position blocking the bK when not playing. An interesting issue is the bBd6. Technically, it could be replaced with a bP, but the author wanted the total number of black pawns and black fairy pieces not to exceed 8. I wouldn’t support such an approach, seeing no logic in it, but respect the author’s choice."
Comments of solvers: "Cycle (as expected!) of promoted piece types. The somewhat limited mobility of these pieces facilitates a neat construction with relatively few blocks. A good idea well set." (CJF), "Complete 3-cycle of white promotee, black promotee and piece blocked by move thereof. Not difficult but again enjoyable; hope'VK will compose more in this style." (CCL), "Not this month, though!" (SE), "Pleasing patterns" (FM).
