Koll, the Forgemaster + Ornithopter + Thermopod

Koll, the Forgemaster

Ornithopter

Thermopod

How it works

1. Activate the Equipment by paying its equip cost, attaching it to Ornithopter.
2. Activate Thermopod by sacrificing Ornithopter, adding .
3. When Ornithopter dies, Koll triggers, returning Ornithopter from your graveyard to your hand.
4. Cast Ornithopter by paying its mana cost.
5. Repeat.

This loop relies on an infinite-loop engine where Ornithopter costs nothing to cast, allowing it to cycle endlessly between the battlefield and your hand. Thermopod serves as the sacrifice outlet that converts each iteration into red mana while also acting as the source for any necessary snow mana to pay your equipment's equip cost. Meanwhile, Koll, the Forgemaster provides the critical recursive trigger, returning the zero-mana flier to your hand whenever it dies as long as it's carrying your equipment, fueling endless death triggers and storm count.
