Greedy Freebooter + Enduring Renewal + Yahenni, Undying Partisan

Greedy Freebooter

Enduring Renewal

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Greedy Freebooter.
2. When Greedy Freebooter dies, it and Enduring Renewal trigger.
3. Resolve the Greedy Freebooter trigger, causing you to scry 1 and create a Treasure token.
4. Resolve the Enduring Renewal trigger, returning Greedy Freebooter from your graveyard to your hand.
5. Resolve the Yahenni ability, giving it indestructible until end of turn.
6. Activate the Treasure by tapping and sacrificing it, adding .
7. Cast Greedy Freebooter by paying .
8. Repeat.

This crafty loop hinges on the elegant synergy between Enduring Renewal's passive replacement effects and its graveyard recursion trigger, which catches your sacrifices mid-flight and bounces them straight back to your hand. Yahenni, Undying Partisan serves as the sacrificial outlet, turning the engine on by gobbling up Greedy Freebooter at instant speed. Each time Greedy Freebooter hits the dirt, it not only triggers the Renewal's return, but its own death ability generously spits out a Treasure token; cracking that very same token immediately funds the mana required to cast Greedy Freebooter all over again.
