Tyranitar

Sand Stream activates Sandstorm on entry for passive chip damage. This Tyranitar runs Speed EVs to creep specific threats rather than the typical max bulk or max Attack spread. Adamant with significant Attack investment ensures hits land hard. Rock Slide spreads flinch damage under Sand. Knock Off removes held items at a critical moment. Crunch is reliable Dark STAB. Low Kick handles opposing Tyranitar, Aggron, and heavy Steel types by weight-scaling. Chople Berry absorbs the Fighting moves that consistently target this team's Steel and Rock Pokémon.
