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 .

This engine creates an infinite loop of scrying and mana generation by turning a simple tap into a cascade of triggers. Attentive Sunscribe provides the tapping and scrying necessary to trigger Arwen Undómiel, which places extra +1/+1 counters onto Crystalline Crawler thanks to the replacement effect from Lae'zel, Vlaakith's Champion. Those added counters can then be stripped away for mana to fuel Freed from the Real, which continuously untaps the Sunscribe to repeat the process.
