This elegant loop turns a modest revival aura into a permanent engine of destiny. With Viscera Seer ready to sacrifice creatures at a moment's notice, Sun Titan can be fed to the seer over and over, while Gift of Immortality neatly bypasses the usual waiting period by returning itself directly to the battlefield attached to the Titan whenever it enters. Because Sun Titan's mana value is low enough to be brought back by its own entrance trigger, every iteration resets the entire loop automatically—letting you scour through your entire library with endless scry triggers and churn out limitless sacrifice synergy.
