Krark-Clan Ironworks + Spine of Ish Sah + Sculpting Steel + Enthusiastic Mechanaut

Krark-Clan Ironworks

Spine of Ish Sah

Sculpting Steel

Enthusiastic Mechanaut

How it works

1. Cast Sculpting Steel by paying 2 due to Enthusiastic Mechanaut. Choose to have it enter as a copy of Spine of Ish Sah.
2. When Sculpting Steel enters, its first ability triggers, destroying a permanent.
3. Activate Krark-Clan Ironworks by sacrificing Sculpting Steel, adding CC.
4. Sculpting Steel's second ability triggers, returning it from your graveyard to your hand.
5. Repeat.

This loop relies on Krark-Clan Ironworks to continuously sacrifice Sculpting Steel (copying Spine of Ish Sah), which triggers its own return to your hand while fueling the mana needed to recast it. Enthusiastic Mechanaut makes this engine cost-efficient by reducing the casting cost of the copies, allowing you to continually redeploy the cloned Spine of Ish Sah to systematically dismantle every permanent your opponents control.
