Excellent discussion guys, keep it coming!
I have included EonX-'s set in the OP but am a bit hesitant about Dat Blast's set. Baton Pass is a good utility move and all, but I don't think it's enough to merit a different set on its own. For this reason, I'll include a "Other Viable Options" section that can act like an AC section used in analyses. I'll add Pursuit and Baton Pass into the viable moves for Absol and Taunt for Houndoom. I also kind of dislike the idea of Super Fang on Mega Houndoom, as honestly, if you can't do over half to the opposing Pokemon with an attacking move, you're better off switching. Also Sergeant Spooky, for the first set you posted, I would recommend Timid > Serious since you're using all special moves and Timid is really nice to outspeed max Speed Latias and Keldeo and Speed tie with the likes of opposing Mega Houndoom and Mega Absol.
That is all for now, but expect some art in the OP soon!
