Blade of the Bloodchief + Thopter Squadron + Krark-Clan Ironworks

Blade of the Bloodchief

Thopter Squadron

Krark-Clan Ironworks

How it works

1. Activate Krark-Clan Ironworks by sacrificing another creature, adding CC.
2. When the creature dies, Blade of the Bloodchief triggers, putting a +1/+1 counter on Thopter Squadron.
3. Activate Thopter Squadron' first ability by paying 1 and removing a +1/+1 counter from it, creating a 1/1 Thopter artifact creature token.
4. Repeat.

This clever loop relies on Thopter Squadron acting as both our mana engine and our counter reservoir, feeding fuel directly into Krark-Clan Ironworks to generate a surplus of colorless mana. As those artifacts and creatures hit the graveyard, Blade of the Bloodchief steps in to continuously rebuild and amplify Thopter Squadron's stock of +1/+1 counters with every single death. By constantly cashing in counters to spawn Thopters and sacrificing them back to the Ironworks, you create a perpetual motion machine that churns out infinite mana alongside an endless procession of enters-the-battlefield, leaves-the-battlefield, and sacrifice triggers.
