1 Tuner + 1+ non-Tuner monsters You can only Special Summon "Shiranui Squiresaga(s)" once per turn. Once per turn: You can banish 1 face-up monster you control or in your GY, then apply these effects, in sequence, depending on what the monster was before it was banished, if it was any of these. ● Zombie: You can have all monsters you control gain 300 ATK. ● FIRE: You can destroy 1 Spell/Trap on the field. ● Synchro: You can destroy 1 monster on the field.
Normal Summon Shiranui Squire or Shiranui Spiritmaster and use their effect to Special Summon Shiranui Spectralsword Shade. Since Shiranui Squiresaga only requires generic Synchro materials, you also have some out of archetype options like Trident Warrior plus a level-3 Tuner but you will miss out on easy graveyard setup.
The Shiranui archetypes main strategy is banishing their own monsters and triggering their effects, usually this is done by other Shiranui monsters as effect cost. Shiranui Squiresaga can banish other Shiranui monsters, from your graveyard preferably, for a slight attack boost and more importantly backrow removal and monster removal.
