Skyshroud Ranger + Amulet of Vigor + Pemmin's Aura + Azorius Chancery

Skyshroud Ranger

Amulet of Vigor

Pemmin's Aura

Azorius Chancery

How it works

1. Activate Skyshroud Ranger by tapping it, putting Azorius Chancery onto the battlefield from your hand.
2. When Azorius Chancery enters the battlefield, it and Amulet of Vigor trigger.
3. Resolve the Amulet of Vigor trigger, untapping Azorius Chancery.
4. Activate Azorius Chancery by tapping it, adding .
5. Resolve the Azorius Chancery 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 clever loop turns a simple scout into an infinite mana engine by exploiting how bounce lands interact with untap triggers. By enchanting Skyshroud Ranger with Pemmin's Aura, you gain the ability to untap the Ranger for a single blue mana, allowing it to repeatedly drop Azorius Chancery onto the battlefield. Because Amulet of Vigor stands watch, the Chancery enters tapped only to immediately untap, letting you tap it for white and blue mana before its own enters-the-battlefield trigger returns it safely back to your hand.
