Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Shame the Isle of Armor mons will be missing this by a month, flipped Azumarill with 50/80/60/80/50/100 stats backed up by Huge Power would be an absolute monster.
The ability description for contrary states "If this Pokemon has a stat stage raised it is lowered instead, and vice versa.", but that's not exactly how it works in gen 7: Status moves used with a Z-crystal effect which boost a Pokemon's stats (EG: conversion) will still increase them even if...
I've been having a lot of success abusing Gale Wings Talonflame:
Lycanroc-Dusk for Tough Claws
Mega Beedrill for Adaptability
Honchkrow for Moxie and to abuse Brave Bird
Hawlucha with Mold Breaker to beat Dazzling/Queenly Majesty teams
and Alakazam for Magic Guard to get rid of Brave Bird recoil
Mega garchomp get's base 170 speed along with it'e usable special attack and excellent movepool (fire blast+draco+earth power+filler)
Togekiss swaps it's offensive stats and gets hustle to boost its 120 attack, shame it no longer gets STAB extremespeed
I personally have had great success using zoroark in the maison, because the AI will never realize that you are, even after the "conkeldurr" has used dark pulse. The set I usually run is nasty plot+flamethrower+dark pulse+grass knot, holding a focus sash
Any objections to me reserving hypno? how about posting his single usable set:
Hypno@sitrus berry
inner focus
248 HP, 252 sp.def, 8 def
trick room
psyshock
dazzling gleam
protect
Hypno is the single viable user of trick room+inner focus
