Emboar

Emboar is the smoking hot Fire-type starter of Gen 5, but isn't as smoking hot in the PvE scene. A few ATK stats behind Blaziken combined with an inferior moveset pretty much makes it irrelevant upon its introduction, since we already had Torchic's Community Day and Blaziken is quite common among players. While Emboar will eventually get its Community Day if the trend continues, being worse than something everyone already has isn't gonna do it any favors. 

Best PvE Offensive Moveset

• Low Kick is the best fast move by a very narrow margin from a stats perspective.
• Ember is right behind it, though its typing does allow Emboar to act as a Fire-type attacker. 
• Blast Burn is the best Charge Move available by a wide margin, and can pair with Ember to fulfill a Fire-type role. 
• Flame Charge falls behind significantly in performance, and other Fire-type Pokemon should be considered instead. 
• Heat Wave is a really bad move. 
• Focus Blast shares the same typing with Low Kick to fulfill a Fighting-type role. 
• Rock Slide lacks STAB and isn't really meaningful for Emboar other than niche uses in attacking gyms. 

Best PvE Defensive Moveset

• Ember hits harder than Low Kick on defense and is more optimal. 
• Rock Slide is the optimal move on defense due to it being a 2-bar move, having a shorter damage window, and good coverage. 
• Blast Burn is arguably the next best Charge Move for defense thanks its huge damage output, but is somewhat easily dodgeable. 
• Flame Charge can be used frequently as a 3-bar move, but a late damage window makes it easy to dodge. 
• Heat Wave might be difficult to access as a 1-bar move, but it's alright for what it does with STAB.
• Focus Blast hits very hard, but is incredibly easy to dodge. 

Ember is the superior choice due to poor performance from Low Kick. 

Rock Slide is mandatory due to its lower energy cost, good coverage, and respectable damage output. Blast Burn is limited to Community Day events and Elite TMs, but deals significantly more Damage Per Energy (DPE) than other Charge Moves available, and is very strong with STAB, even when resisted. Flame Charge isn't particularly strong, but benefits from STAB, and is primarily chosen for its consistent +1 ATK buff even when shielded. Focus Blast is too expensive to use energy-wise, but its wide coverage and high damage can surprise opponents. Don't use Heat Wave, it's bad.
