Stef0w hawlucha steamrolls through stall and offense since he can wallbreak easily and be so fast that he cant be rk thanks to unburden. Short of having priority, sash zam or doublade/granbull, youre pretty screwed. The power herb sd sky attack set is ridiculous.
+2 252+ Atk Hawlucha Sky Attack vs. 252 HP / 252+ Def Slowbro: 267-315 (67.7 - 79.9%) -- guaranteed 2HKO after Leftovers recovery
+2 252+ Atk Hawlucha High Jump Kick vs. 252 HP / 252+ Def Filter Mega Aggron: 213-252 (61.9 - 73.2%) -- guaranteed 2HKO
These are the sturdiest phys walls in UU atm and both are easily 2hko. As for the comment on espeed lucario...
252+ Atk Hawlucha Sky Attack vs. 0 HP / 4 Def Lucario: 264-312 (93.9 - 111%) -- 62.5% chance to OHKO
Keep in mind no boost..
252+ Atk Life Orb Lucario Extreme Speed vs. 8 HP / 0 Def Hawlucha: 140-166 (46.8 - 55.5%) -- 75.8% chance to 2HKO
The only priority user that can reliably rk is fletchinder where acro is guaranteed ohko with no boost.
Tl:dr
Hawlucha can dismantle all styles with ease unless you specifically carry sash zam, doublade, fletchinder or sash cloyster...
