Doom's Time Platform + Shivan Sand-Mage + Capture of Jingzhou + Thassa, Deep-Dwelling

Doom's Time Platform

Shivan Sand-Mage

Capture of Jingzhou

Thassa, Deep-Dwelling

How it works

1. Declare any creature as an attacker. When you do, Doom's Time Platform triggers, exiling Capture of Jingzhou from your graveyard with two time counters on it.
2. Blink Shivan Sand-Mage using Thassa.
3. When Shivan Sand-Mage enters, it triggers, removing two time counters from Capture of Jingzhou.
4. Capture of Jingzhou's suspend ability triggers, causing you to cast it without paying its mana cost.
5. Resolve Capture of Jingzhou, causing you to take an extra turn after this one.
6. Repeat each turn.

This clever loop turns your combat phase into an endless engine of chronological mastery, anchored by Doom's Time Platform tucking Capture of Jingzhou into exile with two time counters whenever you attack. Shivan Sand-Mage accelerates this process by shaving off those final counters the moment it enters the battlefield, but it's Thassa, Deep-Dwelling that truly seals the deal with her recurring end-step blink effect. By repeatedly exiling and returning Shivan Sand-Mage, you ensure that Capture of Jingzhou is cast for free turn after turn, granting you infinite extra turns to dominate the game.
