If you have 2 other Six Samurai on the field when this card would destroy the ones it Special Summoned, simply use their effect to redirect the destruction. Since the summoned monsters aren't destroyed, you would not take damage from the effect (much like how they work against "Ring of Destruction").
Summon two "Spirit of the Six Samurai" and equip them to two existing Six Samurai Monsters, thereby avoiding destroying any cards, in addition to powering up two Six Samurai Monsters.
You can Special Summon 2 "Six Samurai" monster with same level and use them for an "Xyz Summon" without taking any damage.
If you have two copies of "Legendary Six Samurai - Shi En" in the graveyard that were successfully Synchro Summoned previously in the Duel, you can summon both of them with this card. This will give you two 2500 ATK monsters, and the ability to negate up to two Spell or Trap cards, probably resulting in the necessary conditions to win.
