Chulane, Teller of Tales + Retreat to Coralhelm + Nyxbloom Ancient + Selesnya Sanctuary + Archelos, Lagoon Mystic

Chulane, Teller of Tales

Retreat to Coralhelm

Nyxbloom Ancient

Selesnya Sanctuary

Archelos, Lagoon Mystic

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 Selesnya Sanctuary from your hand onto the battlefield untapped due to Archelos.
3. When Selesnya Sanctuary enters, it and Retreat to Coralhelm trigger.
4. Holding priority, activate Selesnya Sanctuary by tapping it, adding due to Nyxbloom Ancient.
5. Resolve the Selesnya Sanctuary trigger, returning it from your hand to the battlefield.
6. Resolve the Retreat to Coralhelm trigger, untapping Chulane.
7. Resolve the creature spell cast in step 1.
8. Activate Chulane by paying 3 and tapping it, returning the creature from the battlefield to your hand.
9. Repeat.

This intricate loop turns a simple land bounce into a massive engine by combining multiple interlocking permanents. Chulane, Teller of Tales acts as your primary enabler, constantly drawing cards and deploying your lands, while Archelos, Lagoon Mystic ensures those lands slip onto the battlefield untapped. Meanwhile, Retreat to Coralhelm untaps Chulane whenever a land arrives, allowing his activated ability to bounce and replay your creatures indefinitely. Nyxbloom Ancient supercharges the whole operation by turning Selesnya Sanctuary's mana production into a massive surplus, providing more than enough resources to sustain the loop while churning through your entire deck.
