Jin-Gitaxias // The Great Synthesis + Time Stretch + Returned Pastcaller

Jin-Gitaxias // The Great Synthesis

Time Stretch

Returned Pastcaller

How it works

1. At the beginning of your precombat main phase, The Great Synthesis triggers, putting a lore counter on it. Its third chapter ability then triggers, causing you to cast Time Stretch and Returned Pastcaller without paying their mana costs, and then exiling The Great Synthesis and returning it to the battlefield as Jin-Gitaxias.
2. Resolve Time Stretch, causing you to take two extra turns after this one.
3. Resolve the Returned Pastcaller spell. When it enters, it triggers, returning Time Stretch from your graveyard to your hand.
4. Activate Jin-Gitaxias by paying 3, exiling it and returning it to the battlefield as The Great Synthesis.
5. When The Great Synthesis enters with a lore counter on it, its first ability triggers, causing you to draw cards equal to the number of cards in your hand and not have a maximum hand size for the rest of the game.
6. Move to your first extra turn. At the beginning of your precombat main phase, The Great Synthesis triggers, putting a lore counter on it. Its second chapter ability then triggers, returning all non-Phyrexian creatures (including Returned Pastcaller) from the battlefield to their owner's hand.
7. Repeat from step 1 during your second extra turn

This fascinating loop achieves near-infinite turns by leveraging the free-casting power of The Great Synthesis's third chapter to cast both Time Stretch and Returned Pastcaller simultaneously. As Returned Pastcaller enters the battlefield, its triggered ability immediately retrieves Time Stretch from your graveyard, ensuring you have the extra turns ready to go. Meanwhile, transforming the Saga back into Jin-Gitaxias—and resetting it—lets you continually reap the hand-refilling benefits of its front face while clearing the board with its second chapter, locking your opponents out of the game entirely.
