Well for Eeveelution you don't have a good physical sweeper. But don't underestimate Flareons attack power:
252+ Atk Guts Flareon Flare Blitz vs. 252 HP / 252+ Def Clefable: 283-334 (71.8 - 84.7%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Guts Flareon Flare Blitz vs. 252 HP / 240+ Def Thick Fat Mega Venusaur: 204-242 (56 - 66.4%) -- guaranteed 2HKO
252+ Atk Guts Flareon Flare Blitz vs. 252 HP / 252 Def Conkeldurr: 264-312 (63.7 - 75.3%) -- guaranteed 2HKO
I mean, with such low speed it won't be sweeping, by it dents a lot of things. You can also use a Curse Pass Umbreon with Wish after special threats have been eliminated.
