Putrid Goblin + Sling-Gang Lieutenant + Thunderous Velocipede

Putrid Goblin

Sling-Gang Lieutenant

Thunderous Velocipede

How it works

1. Activate Sling-Gang Lieutenant by sacrificing Putrid Goblin.
2. When Putrid Goblin dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Thunderous Velocipede.
3. Resolve the Sling-Gang Lieutenant ability.
4. Repeat.

This brilliant loop relies on Thunderous Velocipede’s passive ability to save Putrid Goblin from its own recursion flaw: because the Velocipede bestows a +1/+1 counter when the Goblin enters, that counter instantly cancels out the -1/-1 counter from persist, allowing the Goblin to die and persist over and over again. You fuel this engine by using Sling-Gang Lieutenant to sacrifice Putrid Goblin for a steady stream of life loss and lifegain. The Lieutenant's own entry triggers even help feed the sacrifice costs, creating a relentless loop that drains your opponents out of the game entirely.
