If you could get a Swords Dance off on Midday, it seems like it would be a fun one to mess around with in UU (which is where I feel like it will end up). Not amazing by any means, but beyond Aerodactyl, is their any naturally fast user of STAB Stone Edge? Okay, Archeops, but let me know when it loses Defeatist. Midday just tips out the 110 speed tier, and with 115 base attack, even neutral Stone Edges won't be fun to take, especially after a SD. I'm thinking:
Lycanroc-Midday @ Focus Sash / Life Orb
Ability: Sand Rush
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
Swords Dance
Stone Edge
Crunch / Sucker Punch
Brick Break / Elemental Fang
Life Orb if you think you can find an opportunity to safely Swords Dance. It doesn't use Accelerock, but it seems like it could be decently fun to use with it's speed. Alternatively it could be decent revenge killer with a Choice Band, and replace Swords Dance with Accelerock or extra coverage. I'm not really sure what either of the elemental fangs would hit harder than a neutral STAB Stone Edge in UU, but somebody more familiar with the tier could probably say what the coverage would help.
