This clever loop transforms a humble land into a lethal engine using Sydri, Galvanic Genius to temporarily animate Seat of the Synod as an artifact creature with zero toughness. Because a zero-toughness creature instantly dies as a state-based action, its demise immediately triggers Salvaging Station to untap itself. You can then tap Salvaging Station to return that very same Seat of the Synod straight from the graveyard back to the battlefield, ready to be animated and sacrificed all over again.
