I'm surprised both Scarf Garchomp and Scarf Terrakion aren't mentioned in the OP. Honestly, they're probably the best Scarfers along with Lando-T now the Genesect is gone, as their high base Speed means they're great revenge killers. They both function similarly, though they do have their differences. Garchomp has a more spammable STAB in Outrage/Dragon Claw, while Terrakion has higher base Speed. Anyways, here are the sets.
Garchomp @ Choice Scarf
Ability: Rough Skin
EVs: 252 Spd / 252 Atk / 4 Def
Naive / Jolly
- Outrage
- Earthquake
- Fire Blast / Dragon Claw
- Stone Edge
Terrakion @ Choice Scarf
Ability: Justified
EVs: 252 Spd / 252 Atk / 4 SDef
Jolly Nature
- Close Combat
- Stone Edge
- Earthquake
- X-Scissor
Both sets are pretty simple. Garchomp runs dual STABs, as they are near un-resisted. Fire Blast can hit Skarmory and Ferrothorn, though Dragon Claw can be used if your fear having to lock yourself into Outrage. Finally, Stone Edge is used to revenge kill Pokemon like Charizard Y, Volcarona, and Togekiss. A Naive nature is used with Fire Blast in order to make sure both attacks hit as hard as possible while also allowing Garchomp to be extremely fast. However, if Fire Blast isn't being used, a Jolly nature is preferred. Max Atk and max Speed allows Garchomp to be as fast and as powerful as possible.
Terrakion runs dual STABs as well, as they too are near un-resisted. Earthquake gives Terrakion a way to hit Aegislash, while X-Scissor is a more reliable way to hit Psychic-types. A Jolly nature with max Attack and max Speed is used to allow Terrakion to hit as hard as possible while also making him extremely speedy.
Anyways, these two Pokemon, in my opinion, are probably the two best Choice Scarf users atm (along with Lando-T.) Overall, while Choice Scarf may not be as helpful as it used to be with all the priority in OU, it can still be a great item when utilized correctly.
