Long Feng, Grand Secretariat + Krark-Clan Ironworks + Thopter Squadron

Long Feng, Grand Secretariat

Krark-Clan Ironworks

Thopter Squadron

How it works

1. Activate Thopter Squadron by paying 1 and removing a +1/+1 counter from it, creating a creature token.
2. Activate Krark-Clan Ironworks by sacrificing the creature token, adding CC.
3. When the creature token dies, Lord Feng triggers, putting a +1/+1 counter on Thopter Squadron.
4. Repeat.

This clever engine transforms a modest mechanical loop into a powerhouse of endless resources, fueled by Long Feng, Grand Secretariat, whose triggered ability quietly rewards every single sacrifice with fresh growth. You begin by sinking one mana into Thopter Squadron to strip away a +1/+1 counter and mint a 1/1 flying token, which immediately feeds into Krark-Clan Ironworks to convert that token into two colorless mana. Because the dying token triggers Long Feng, Grand Secretariat, you can direct the resulting +1/+1 counter right back onto Thopter Squadron, leaving you with net-positive mana and a fully restored counter to repeat the process indefinitely.
