Looking for Clues in All the Wrong Places - A FullDeck & Missing a Few Cards extravaganza

Today's Video:

I am very lucky to have two of the best Sudoku variant constructors out there to create a puzzle dedicated to this channel.

Word of warning from these two "It's far too hard for your usual channel fare so we're absolutely NOT suggesting that you do a video solve of it."

Do enjoy this incredible creation :D

Rules:

**Sudoku, Whisper-4, Renban, Sleuths, Footprints**

- Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Whisper-4 Lines: Adjacent digits along a Whisper-4 Line (the magnifying glass and handle in this puzzle) differ by at least 4 - Renban Lines: Digits along a Renban line (the question mark and the shadow of the magnifying glass in this puzzle) must form a set of non-repeating consecutive digits in any order. - Sleuths: All of the cells with a sleuth contain the same digit. - Footprints: Digits in cells separated by a pair of footprints are in a 1:2 ratio.
