How it works
Cast Sculpting Steel by paying 2 due to Lyse Hext.
Lyse Hext's prowess ability triggers, giving it +1/+1 until end of turn.
Resolve Sculpting Steel. Choose to have it enter as a copy of Spine of Ish Sah.
When Sculpting Steel enters, its first ability triggers, destroying a permanent.
Activate Krark-Clan Ironworks by sacrificing Sculpting Steel, adding CC.
Sculpting Steel's second ability triggers, returning it from your graveyard to your hand.
Repeat.
This looping destruction engine feeds on the mana-producing sacrifice outlet Krark-Clan Ironworks to repeatedly churn out copies of Spine of Ish Sah. By leveraging Sculpting Steel to enter the battlefield as an additional Spine of Ish Sah, you trigger its enter-the-battlefield ability to systematically wipe out every permanent your opponents control. Furthermore, because Sculpting Steel's second ability triggers when it is put into a graveyard from the battlefield, it conveniently returns right back to your hand to start the cycle anew. Meanwhile, Lyse Hext quietly reduces the casting cost of your noncreature spells by {1} and gains prowess along the way, turning your relentless artifact loop into a lethal, game-locking assault.
