Role: Tank / Hazard Setter
Tyrantrum @ Leftovers
Ability: Strong Jaw
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Curse
- Poison Fang
- Stealth Rock
- Roar
Basically, you set up the stealth rocks, then you can curse to get bulkier, roar to have the opponent take stealth rock damage, or poison fang to try and poison them. With the EVs, he can survive a few attacks, even if they are special.
This is a weird set for Tyrantrum, but I think it works.
