Attentive Sunscribe + Arwen Undómiel + Crystalline Crawler + Freed from the Real + Pir, Imaginative Rascal

Attentive Sunscribe

Arwen Undómiel

Crystalline Crawler

Freed from the Real

Pir, Imaginative Rascal

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 infinite loop relies on a clever mana-positive counter cycle centered around Attentive Sunscribe enchanted with Freed from the Real. Tapping the Sunscribe triggers its scry ability, which in turn causes Arwen Undómiel to distribute amplified +1/+1 counters to Crystalline Crawler thanks to Pir, Imaginative Rascal's replacement effect. You then harvest those extra counters off the Crawler for mana to feed the Freed from the Real untap ability, leaving you with infinite scrying power.
