Very interesting thread here, it's nice to see that the concept of Lead isn't truly dead with Team preview.
So...
Terrakion @ Focus Sash Trait: Justified
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Close Combat
- Stone Edge
- Stealth Rock
- Taunt
Quite unexpected, fast SR User who at the same times scares off the opponent, we all know how scary is the fight+rock coverage as of now, Terrakion is truly an amazing sr user, since he causes many switchs, most of the time he can also weaken the opposing team, gold examples here would be Breloom and Scizor, who will take a good blow against Focus Sash Terrakion.
