Mega Tyranitar

Sand Stream activates Sandstorm on entry and Mega Evolution, immediately enabling Excadrill's Sand Rush speed doubling. Knock Off removes held items at the turn of entry. Stripping Berries, Choice Scarves, and Sitrus Berries before opponents can use them. Rock Slide spreads chip and flinch against both opponents. Low Kick handles heavy Steel and opposing Rock types by weight scaling. Protect allows safe positioning. Adamant with balanced HP and Speed EVs creates a Tyranitar that sets weather and applies consistent physical pressure. Fast enough to establish Sandstorm before opposing weather setters can respond and overwrite it.
