Offensive Garchomp often faces faster opponents capable of one-shotting it before it can act. The Focus Sash allows Garchomp to survive any single hit from full HP, negating this immediate vulnerability. This tactical advantage ensures Garchomp a turn to strike back with a powerful move or perform a utility action like Stealth Rock or Swords Dance. This strategy effectively turns a predicted knockout into a forced trade or even a game-changing setup opportunity, particularly against threats like Dragapult or Mega Froslass that would otherwise outspeed and eliminate Garchomp.
