Krark-Clan Ironworks + Spine of Ish Sah + Sculpting Steel + Ballad of the Black Flag

Krark-Clan Ironworks

Spine of Ish Sah

Sculpting Steel

Ballad of the Black Flag

How it works

1. Cast Sculpting Steel by paying 2 due to Ballad of the Black Flag. 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 devastating loop relies on the cost reduction from Ballad of the Black Flag's final chapter to recast Sculpting Steel as a copy of Spine of Ish Sah over and over. Each time the copied Spine enters the battlefield, its triggered ability blows up another permanent, effortlessly stripping your opponents of their entire board. Krark-Clan Ironworks then provides the engine fuel by sacrificing the copied Spine for mana, which simultaneously triggers the original card's fallback clause to return it safely back to your hand.
