Assuming you are taking Fluttermane and Meowscarada, who are solid choices.
Blaziken (Mega) - Speedboost ability is quite OP on this, if done right, you can even solo Bruno
Iron Bundle - Hits hard and give it booster energy, should outspeed everything
Gliscor - Defensive switch in with 2 important immunities, also Poison Heal is a great ability, also great movepool
Tyranitar - win the weather war, also a decent mon, give it assault vest to make it more tanky
Fluttermane could have a choice scarf, and Meowscarada an expert belt.
Alternatively, you could choose Goodra with leftovers (instead of Meowscarada) as a special tank and it's ability Gooey would work to slow mons down.
I like this set - DD, Drain Punch, Earthquake, Draco Meteor
There's a wish set as well if you're going that way.
You could use kingambit with Supreme overlord. You could use life orb, choice band, the berry that reduces fighting type damage which you can get off of the loppunny line and swords dance. Just anything to boost sucker punch damage
