Okay, in the current meta, the one area in which Emboar excels is against hail teams due to it's excellent typing, powerul moves, and decent typing. To take complete advantage of his anti-hail typing, and the ladder's reckless sacrifice of Snover I propose the following set.
Emboar @ Life Orb
Trait: Blaze
EVs: 252 Atk / 176 Spd / 80 SAtk
Naughty Nature
- Sunny Day
- SolarBeam
- Flare Blitz
- Stone Edge
This Emboar not only aims to destroy hail teams, but it also is able to get around some of its usual counters for example:
80 SpA Life Orb Emboar SolarBeam vs. 252 HP / 4 SpD Alomomola: 452-533 (84.64 - 99.81%) -- 81.25% chance to OHKO after Stealth Rock.
252+ Atk Life Orb Emboar Flare Blitz vs. 248 HP / 144 Def Slowking in sun: 205-242 (52.16 - 61.57%) -- guaranteed 2HKO after Stealth Rock
80 SpA Life Orb Emboar SolarBeam vs. 248 HP / 116+ SpD Slowking: 185-218 (47.07 - 55.47%) -- guaranteed 2HKO after Stealth Rock. Both solar beam and Flareblitz in the sun are a 2HKO against Slowking, easing prediction against the most common mon in the tier.
80 SpA Life Orb Emboar SolarBeam vs. 252 HP / 4 SpD Poliwrath: 265-312 (69.01 - 81.25%) -- guaranteed 2HKO after Stealth Rock
Stone Edge is chosen in the last slot over other moves as it allows perfect neutral coverage in the tier (I think). More specifically it hits, Altaria, Moltres and Druddigon hard outside of the sun, something that most Emboar's struggle with already. The speed investment is enough to outspeed neutral base 55's such as Crawduant, while speed-tying 16 speed Qwilfish, an important speed tier in RU. Life orb is chosen over heat rock, as Emboar has both the ability to force out opposing mons, and the defenses to set up sun more than once, and life orb is the necessary to provide Emboar with support. This set excels on bulky offensive teams that struggle with hail, but Emboar really appreciates wish support from something like Alomomola or Clefable, as life orb and flareblitz recoil add up pretty quickly. Lastly, and most importantly, fuck Hail.
