Su-Chi Cave Guard + Enduring Renewal + Krark-Clan Ironworks

Su-Chi Cave Guard

Enduring Renewal

Krark-Clan Ironworks

How it works

1. Activate Krark-Clan Ironworks by sacrificing Su-Chi Cave Guard, adding CC.
2. When Su-Chi Cave Guard dies, it and Enduring Renewal trigger.
3. Resolve the Su-Chi Cave Guard trigger, adding eight C.
4. Resolve the Enduring Renewal trigger, returning Su-Chi Cave Guard from your graveyard to your hand.
5. Cast Su-Chi Cave Guard by paying 8.
6. Repeat.

This looping engine turns a mechanical sacrifice cycle into an unstoppable cascade of colorless energy. By feeding Su-Chi Cave Guard to Krark-Clan Ironworks, you generate the exact amount of mana needed to cast it again, while Enduring Renewal catches the construct as it hits the graveyard and effortlessly bounces it right back to your hand.
