1.2x Damage Boost to All Damaging Moves in Masked Forms

When Ogrepon has a Mask Held Item (Wellspring Mask, Hearthflame Mash, or Cornerstone Mask, not the Teal Mask base form), it receives an additional 20% damage boost on all moves, regardless of whether they are STAB or not.

This bonus also applies even if Ogrepon is not Terastallized. This amounts to a total of a 1.7x damage boost when accounting for STAB + Mask Boost. If Terastallized and using a move which matches the Tera Type, this reaches up to a 2.2x Damage boost!

How to Use Hearthflame Mask Ogerpon (Fire) Effectively

Use its Strong Fire and Grass Typing

Fire and Grass are a unique offensive type combination that hasn't been seen outside of Scovillain. Make sure to use its strong STAB coverage moves to keep your opponent on their toes.

How to Build a Team with Hearthflame Mask Ogerpon (Fire)

Hearthflame Ogerpon is naturally suited to Sun Teams. Tornadus can manually set up Sun, while Torkoal can set it up when it enters the field, and can even support it with Yawn.

Sample Singles Teams

Focus Sash Lead	Physical Attacker	Special Attacker
Glimmora	Ogerpon (Hearthflame Mask)	Flutter Mane

Ogerpon Hearthflame Mask is best used on a fast hyper offense team in order to best use its unique Fire / Grass typing. Terastallizing to activate Embody Aspect's Attack boost will also help ensure easy knock outs.

Use Glimmora or other hazard setters as your lead to cause chip damage with moves like Stealth Rock to break any Focus Sashes and have another fast Pokemon with strong coverage like Flutter Mane in the back.

Sample Doubles Teams

Support / Special Attacker	Physical Attacker
Tornadus (Incarnate Forme)	Ogerpon (Hearthflame Mask)
Special Attacker	Physical Attacker
Torkoal	Flutter Mane

Tornadus is able to support Ogerpon with Tailwind, as well as set up Sun for it so that it can use powerful, Sun-boosted Ivy Cudgels.

Torkoal can also set up Sun, and provide Yawn support if necessary.

Flutter Mane can improve the team's match up against Chien-Pao and Dragonite, being immune to Extreme Speed, and being able to threaten both with Fairy-type attacks. It also has natural synergy with Sun because of Protosynthesis.
