Attentive Sunscribe

Arwen Undómiel

Crystalline Crawler

Freed from the Real

Ozolith, the Shattered Spire

How it works

1. Activate Freed from the Real's first ability by paying , tapping Attentive Sunscribe.
2. Attentive Sunscribe triggers, causing you to scry 1.
3. Arwen Undómiel triggers, putting two +1/+1 counters on Crystalline Crawler.
4. Activate Crystalline Crawler's first ability twice by removing two +1/+1 counters from it, adding .
5. Activate Freed from the Real's second ability by paying , untapping Attentive Sunscribe.
6. Repeat.

This fascinating mana-positive loop centers around enchanting Attentive Sunscribe with Freed from the Real, allowing you to tap and untap the creature repeatedly for a single blue mana. Every time Attentive Sunscribe becomes tapped, its triggered ability lets you scry 1, which in turn causes Arwen Undómiel to trigger and place counters on Crystalline Crawler. Thanks to Ozolith, the Shattered Spire increasing that counter production by one extra counter each time, Crystalline Crawler grows rapidly instead of depleting. You can then spend Crystalline Crawler's ability to remove those accumulated counters for mana, fueling the loop indefinitely while generating infinite scry triggers.
