Walking Wake can very easily switch into the standard Ceruledge immediately if it wants to. It x4 resists Edge's Bitter Blade, and Shadow Sneak isn't exactly known for its high base power. Edge can't afford to Swords Dance while Wake is in the back either, because all the opponent has to do is hard switch into it, take pittance from whatever attack and cleanly OHKO back with either of its STABs.
244 SpA Choice Specs Walking Wake Hydro Steam vs. 0 HP / 4 SpD Ceruledge: 378-446 (129.8 - 153.2%) -- guaranteed OHKO
244 SpA Choice Specs Walking Wake Draco Meteor vs. 0 HP / 4 SpD Tera Fighting Ceruledge: 306-361 (105.1 - 124%) -- guaranteed OHKO
The best Ceruledge can hope for is to immediately Tera Fighting and Close Combat on the switch
252 Atk Tera Fighting Ceruledge Close Combat vs. 12 HP / 0 Def Walking Wake: 207-244 (60.5 - 71.3%) -- 75% chance to OHKO after Stealth Rock and 3 layers of Spikes
While its true that its in Edge's favor to pick up the KO with all those hazards up and that even if it misses Shadow Sneak can finish it off, finding the time to put up Rocks
and 3 layers of Spikes beforehand is still a tall order even now that the SV metagame makes hazards easier to maintain.
Also, without Terastallization being available to Edge anymore...
252 Atk Ceruledge Close Combat vs. 12 HP / 0 Def Walking Wake: 138-163 (40.3 - 47.6%) -- guaranteed 3HKO

This is a slight variation on Edge's usual Bulk Up set, with more speed, physical defense instead of special defense and Destiny Bond over Taunt. With 224 EVs in Speed, Edge can always outspeed Wake after Weak Armor procs a single time, even under Sun. The idea here is that you switch Edge into any physical attack, preferably a resisted one, Bulk Up once as said attacker switches into Wake and Destiny Bond. (Alternatively, switching Edge directly into a U-Turn allows you to skip the second step entirely.) Hydro Steam should still OHKO Edge, but that's exactly what you want, since Destiny Bond will kill Wake in return.

If Wake plays around the Destiny Bond with its other moves, you have the option to Terastallize Edge or not, depending on what Wake locks into instead. If it Pulses or Dracos (and misses the KO with the latter, which it's likely to), Tera-Fairy shuts it down from there and lets Edge return to setting up. If Wake Flamethrowers, Edge outdamages it with Sneak if Sun's not up, and if it is, it can literally just click anything else (twice even, unless Wake had been high-rolling) and Destiny Bond again.
244 SpA Choice Specs Walking Wake Flamethrower vs. 248 HP / 0 SpD Ceruledge: 71-84 (20.1 - 23.7%) -- guaranteed 5HKO
244 SpA Choice Specs Walking Wake Flamethrower vs. 248 HP / 0 SpD Ceruledge in Sun: 107-126 (30.3 - 35.6%) -- 34.1% chance to 3HKO
Shadow Claw is slashed in alongside Sneak in case you want more power over priority. Specifically, it can 2HKO Wake at +2, which can be handy if it locks into Flamethrower and Sun's not up.
+2 0 Atk Ceruledge Shadow Claw vs. 12 HP / 0 Def Walking Wake: 198-234 (57.8 - 68.4%) -- guaranteed 2HKO
+2 0 Atk Ceruledge Shadow Sneak vs. 12 HP / 0 Def Walking Wake: 114-135 (33.3 - 39.4%) -- guaranteed 3HKO

Funnily enough, Ceruledge also gets Dragon Claw, which was the first thing I tried to make work. However, a Swords Dance set won't appreciate replacing any of its other moves for Dragon Claw, and it needs both Swords Dance up
and a Weak Armor proc before it can work properly. Of course, that wouldn't have been a problem had U-Turn not existed, but it does... so it is...
I did keep that Weak Armor proc necessity in mind for when I would ultimately commit to Destiny Bond, but I figured I'd take a crack at a Choice Band set first. Unfortunately, Band isn't quite powerful enough to secure the KO on its own; Edge needs to be Adamant and Rocks need to be up at the time to get the clean roll to happen.
252 Atk Choice Band Ceruledge Dragon Claw vs. 12 HP / 0 Def Walking Wake: 276-326 (80.7 - 95.3%) -- guaranteed 2HKO/50% chance to OHKO after Stealth Rock/1 layer of Spikes
252+ Atk Choice Band Ceruledge Dragon Claw vs. 12 HP / 0 Def Walking Wake: 302-356 (88.3 - 104%) -- 25% chance to OHKO/guaranteed OHKO after Stealth Rock/1 layer of Spikes
