Skyshroud Ranger

Amulet of Vigor

Pemmin's Aura

Simic Growth Chamber

How it works

1. Activate Skyshroud Ranger by tapping it, putting Simic Growth Chamber onto the battlefield from your hand.
2. When Simic Growth Chamber enters the battlefield, it and Amulet of Vigor trigger.
3. Resolve the Amulet of Vigor trigger, untapping Simic Growth Chamber.
4. Activate Simic Growth Chamber by tapping it, adding .
5. Resolve the Simic Growth Chamber trigger from step 2, returning it to your hand from the battlefield.
6. Activate Pemmin's Aura's first ability by paying , untapping Skyshroud Ranger.
7. Repeat.

This loop achieves infinite green mana and landfall triggers by exploiting the self-bouncing nature of bouncelands alongside a clever untap engine. When you use Skyshroud Ranger to drop Simic Growth Chamber straight from your hand, Amulet of Vigor immediately steps in to untap the land as it enters, allowing you to tap it for mana before its own trigger forces it back to your hand. Meanwhile, Pemmin's Aura provides the necessary untap capability for your Ranger using a portion of the blue mana you generated, resetting the creature so you can replay the land all over again.
