Alesha, Who Smiles at Death

Crystalline Crawler

Aggravated Assault

Arcbound Overseer

Arcbound Ravager

How it works

1. Activate Crystalline Crawler's second ability by tapping it, putting a +1/+1 counter on it.
2. Activate Arcbound Ravager by sacrificing Arcbound Overseer.
3. When Arcbound Overseer dies, it triggers, putting its +1/+1 counters on Crystalline Crawler.
4. Resolve the Arcbound Ravager ability.
5. Activate Crystalline Crawler's first ability five times by removing five +1/+1 counters from it, adding 3.
6. Activate Aggravated Assault by paying 3, causing you to untap all creatures you control and to get an additional combat and main phase after this one.
7. Declare Alesha as an attacker, triggering its ability, targeting Arcbound Overseer.
8. Activate Crystalline Crawler's first ability twice by removing two +1/+1 counters from it, adding W/BW/B.
9. Resolve the Alesha trigger, causing you to pay W/BW/B to return Arcbound Overseer from your graveyard to the battlefield tapped and attacking with six +1/+1 counters on it due to its modular ability.
10. Repeat.

This clever setup turns a mechanical loop into a relentless assault by utilizing Crystalline Crawler as your personal mana battery, converting its counters into the exact fuel needed to power Aggravated Assault for infinite combat phases. Meanwhile, Arcbound Ravager provides a reliable way to cycle your pieces to the graveyard, setting up Alesha, Who Smiles at Death to march back into battle and resurrect Arcbound Overseer with every new attack. Whenever Arcbound Overseer returns, its modular ability smoothly funnels its counters right back into Crystalline Crawler, sustaining the engine's mana production so you can repeat the cycle endlessly.
