This is the Tyrunt I run on Showdown:
Tyrunt @ Choice Band/Life Orb
Ability: Strong Jaw/Sturdy
EVs: 204 Atk / 236 SDef / 68 Def
Adamant Nature
- Crunch/Dragon Dance
- Dragon Claw-STAB
- Stone Edge-STAB
- Ice Fang/DragonDance
Sturdy works with DragonDance while Strong Jaw works with Crunch and Ice Fang, your choice really.
If you go with the Life Orb and Sturdy moveset you can (obv) replace either Crunch or Ice Fang for Dragon Dance (Crunch has more power while Ice Fang has more coverage)
bold= one moveset and Italics= the other
