Chulane, Teller of Tales

Retreat to Coralhelm

Nyxbloom Ancient

Amulet of Vigor

Simic Growth Chamber

How it works

1. Cast the creature in your hand by paying its mana cost.
2. Chulane triggers, causing you to draw a card and put Simic Growth Chamber from your hand onto the battlefield.
3. When Simic Growth Chamber enters, it, Amulet of Vigor and Retreat to Coralhelm trigger.
4. Resolve the Amulet of Vigor trigger, untapping Simic Growth Chamber.
5. Holding priority, activate Simic Growth Chamber by tapping it, adding due to Nyxbloom Ancient.
6. Resolve the Simic Growth Chamber trigger, returning it from your hand to the battlefield.
7. Resolve the Retreat to Coralhelm trigger, untapping Chulane.
8. Resolve the creature spell cast in step 1.
9. Activate Chulane by paying 3 and tapping it, returning the creature from the battlefield to your hand.
10. Repeat.

This intricate loop centers around Chulane, Teller of Tales, who continuously fuels your hand and drops lands whenever a creature enters the battlefield. Retreat to Coralhelm provides the crucial untap trigger for Chulane each time Simic Growth Chamber enters, while Amulet of Vigor ensures the bounce land arrives ready to be tapped immediately. The real engine of abundance here is Nyxbloom Ancient, whose explosive mana multiplication turns a single activation of Simic Growth Chamber into more than enough green and blue mana to fund Chulane's activation cost and replay your creature over and over.
