This elegant loop centers on Deadbridge Chant's upkeep trigger, which turns your graveyard into a random lottery where every single prize is devastating. By using Tormod's Cryptkeeper to completely exile your graveyard beforehand, you guarantee that Time Stretch is the *only* card resting in your boneyard, ensuring the Chant blindly scoops it straight back to your hand every single time. From there, you simply cast Time Stretch to take two extra turns, safely bridging the gap until the Chant triggers again to repeat the entire sequence.
