Interesting.

Solutions: Remote Pairs (14) is a single shot. The apparent UR (14) is invalid, yet does solve the puzzle. Or a two stepper: x-wing (4) with a xyz-wing (147) accomplishes the same thing as the remote pair.

I used Earl's 1st step.

I can't remember the last time there were consecutive VHs.

The 12-5 XY-wing is a one-stepper.
