Koll, the Forgemaster + Ronin Warclub + Shield Sphere + Goblin Bombardment

Koll, the Forgemaster

Ronin Warclub

Shield Sphere

Goblin Bombardment

How it works

1. Cast Shield Sphere by paying 0.
2. When Shield Sphere enters the battlefield, Ronin Warclub triggers, attaching Ronin Warclub to Shield Sphere.
3. Activate Goblin Bombardment by sacrificing Shield Sphere.
4. When Shield Sphere dies, Koll triggers, returning Shield Sphere from your graveyard to your hand.
5. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
6. Repeat.

This clever loop harnesses **Koll, the Forgemaster** to turn zero-mana artifacts into an endless barrage of sacrifice fodder. Because **Shield Sphere** costs nothing to cast and immediately equips **Ronin Warclub** upon entering the battlefield, it qualifies as both enchanted or equipped when it dies. When you feed **Shield Sphere** to **Goblin Bombardment** to ping any target, **Koll, the Forgemaster**'s triggered ability catches it on the way out and bounces it straight back to your hand. You can then replay the **Shield Sphere** for free, automatically re-triggering **Ronin Warclub** and **Goblin Bombardment** anew for an unstoppable chain of fiery destruction.
