Unspeakable Symbol + Sage of Hours + Gray Merchant of Asphodel + Teleportation Circle

Unspeakable Symbol

Sage of Hours

Gray Merchant of Asphodel

Teleportation Circle

How it works

1. At the beginning of your end step, Teleportation Circle triggers, blinking Gray Merchant of Asphodel.
2. When Gray Merchant of Asphodel enters the battlefield, it triggers, causing each opponent to lose life equal to your devotion to black, and you to gain life equal to the life lost this way.
3. Activate Unspeakable Symbol five times by paying 15 life, putting five +1/+1 counters on Sage of Hours.
4. Activate Sage of Hours by removing all +1/+1 counters from it, causing you to take at least one extra turn after this one.
5. Repeat each turn.

This intricate loop turns your life total into an endless stream of time by feeding the heroic growth of Sage of Hours. While Unspeakable Symbol converts your life total directly into the exact five +1/+1 counters the Sage needs to unlock an extra turn, Teleportation Circle quietly keeps the engine going by blinking Gray Merchant of Asphodel at every end step. Each time that Merchant re-enters the battlefield, its devotion-based life drain replenishes the very life total you spent fueling the Symbol, letting you safely repeat the entire process across infinite turns until your opponents are drained away.
