Bhaal, Lord of Murder + Crystalline Crawler + Gravecrawler + Viscera Seer

Bhaal, Lord of Murder

Crystalline Crawler

Gravecrawler

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing Gravecrawler.
2. When Gravecrawler dies, Bhaal triggers, putting a +1/+1 counter on Crystalline Crawler.
3. Resolve the Viscera Seer ability, causing you to scry 1.
4. Activate Crystalline Crawler's first ability by removing a +1/+1 counter from it, adding .
5. Cast Gravecrawler from your graveyard by paying .
6. Repeat.

This elegant loop relies on Gravecrawler's ability to repeatedly crawl back from the graveyard, made possible because you continuously control a Zombie (the Gravecrawler itself) and have a black mana source. That crucial mana is generated by Crystalline Crawler, which funds the casting cost by converting counters into fuel. Meanwhile, Bhaal, Lord of Murder turns every single sacrifice into growth by placing a fresh +1/+1 counter back onto Crystalline Crawler, replenishing its energy while Viscera Seer lets you sift endlessly through your library with scry triggers.
