Roalesk, Apex Hybrid + Blade of Shared Souls + Sporoloth Ancient + Crystalline Crawler

Roalesk, Apex Hybrid

Blade of Shared Souls

Sporoloth Ancient

Crystalline Crawler

How it works

1. Activate Blade of Shared Souls' equip ability by paying 2, attaching it to another creature you control.
2. Blade of Shared Souls triggers, causing the creature it is attached to to become a copy of Roalesk.
3. Put the creature with Blade of Shared Souls attached into your graveyard due to the legend rule.
4. The creature triggers, putting two spore counters on Sporoloth Ancient and two +1/+1 counters on Crystalline Crawler.
5. Activate Sporoloth Ancient by removing two spore counters from it, creating a 1/1 Saproling creature token.Activate Crystalline Crawler's first ability twice by removing two +1/+1 counters from it, adding 2.
6. Repeat.

This clever loop revolves around turning a copy of Roalesk, Apex Hybrid into a relentless sacrifice engine using the clone effect of Blade of Shared Souls. Because the newly copied creature immediately hits the graveyard to the legend rule, Roalesk's death trigger fires off a cascade of double proliferation that feeds right back into your board state. Meanwhile, Sporoloth Ancient passively grants your creatures the ability to spend accumulated spore counters to churn out Saproling tokens, and Crystalline Crawler acts as both a battery for mana and a recipient for counters, allowing you to sustain the {2} equip cost of Blade of Shared Souls indefinitely.
