As I said it isn't super amazing (its hard to build around a fighting type that is weak to dark :/) but it is kinda cool. Basically my thought process was the following: Meloetta-P is rendered almost useless by ghosts, and Sneasel can help deal with that by Pursuit trapping them, as well as generally weakening physical walls with Knock Off, and cleaning up pretty easily against offense. At this point I was super weak to fighting types, so Qwilfish seemed like the most logical choice, on top of checking most fighting types well, it also provides spike support, which is nice for getting that extra damage on top of pursuit, and also since Meloetta-P can cause double switches if played correctly. I was weak to Jolteon / Electrics and needed SR, hence the Mega Steelix, which is just generally good right now. Now at this point I said, hey I gone done fucked up again, as my "defensive backbone" (still an offensive team) was weak to ground, so I solved this by adding roost U-turn 2 Special Attacks Flygon which beats all relevant ground-types in the tier and can lure in and U-turn out of Jellicent for Sneasel to trap. I was once again weak to fight, and also Alomomola, and just kinda stall, so I added in CM Psycho Shift Sigi with Air Slash, as this generally does that, this spread always survives a LO 4 Atk Houndoom Sucker Punch from full health, and has like a 50% chance to 2hko doomer w/o rocks (100% chance to 2HKO with rocks). Houndoom is kind of a threat, but Flygon can play around it, and it literally can't switch on anything except you using hazards, so you just have to be careful of that. I wouldn't bring this to some super important match, but its p fun for laddering or w/e. Hope you like it n_n. Also I changed your Meloetta set a little bit, as you are often Relic Songing on like Mola or something that can status you and Facade is pro.
