Koll, the Forgemaster + Demonmail Hauberk + Crookshank Kobolds + Ornithopter

Koll, the Forgemaster

Demonmail Hauberk

Crookshank Kobolds

Ornithopter

How it works

1. Activate Demonmail Hauberk's equip ability by sacrificing Crookshank Kobolds, targeting Ornithopter.
2. When Crookshank Kobolds dies, Koll triggers, returning Crookshank Kobolds from your graveyard to your hand.
3. Resolve the Demonmail Hauberk ability, attaching it to Ornithopter.
4. Cast Crookshank Kobolds by paying 0.
5. Activate Demonmail Hauberk's equip ability by sacrificing Ornithopter, targeting Crookshank Kobolds.
6. When Ornithopter dies, Koll triggers, returning Ornithopter from your graveyard to your hand.
7. Resolve the Demonmail Hauberk ability, attaching it to Crookshank Kobolds.
8. Cast Ornithopter by paying 0.
9. Repeat.

This ingenious loop is powered by the synergy between Koll, the Forgemaster and Demonmail Hauberk, using the equipment's alternate equip cost to perpetually feed creatures to the graveyard. By alternating sacrifices between the free-to-cast Crookshank Kobolds and Ornithopter, you satisfy the equipment's demand for a sacrifice while ensuring that Koll's triggered ability always finds an enchanted creature to bounce back to your hand. Because both creatures cost zero mana to cast, you can endlessly replay them, sacrifice them, and return them, generating an infinite storm count alongside limitless entry, death, and sacrifice triggers.
