If you read the first post, I said that I'm not adding all Gen IV and V moves. I added 113 new moves, most from Gen IV, some from Gen V, and some custom moves. Scald was never in HG/SS, it's a Gen V move, and it's also a move that is one of the 113 added moves in DarkViolet.
From the first post:
And yes, Signal Beam is still a move. No moves were deleted.
