Scourge of Nel Toth + Infested Thrinax + Pitiless Plunderer + Bloodflow Connoisseur

Scourge of Nel Toth

Infested Thrinax

Pitiless Plunderer

Bloodflow Connoisseur

How it works

1. Cast Infested Thrinax by paying 3
2. When Infested Thrinax enters the battlefield, it triggers, causing you to create a number of 1/1 Saproling creature tokens when a nontoken creature you control dies.
3. Activate Bloodflow Connoisseur by sacrificing Scourge of Nel Toth.
4. When Scourge of Nel Toth dies, Infested Thrinax and Pitiless Plunderer trigger.
5. Resolve the Infested Thrinax trigger, creating six 1/1 Saproling creature tokens.
6. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
7. Activate Bloodflow Connoisseur by sacrificing a Saproling.
8. When the Saproling dies, Pitiless Plunderer triggers, creating a Treasure token.
9. Resolve the Bloodflow Connoisseur abilities from steps 3 and 7, putting two +1/+1 counters on it.
10. Activate two Treasures by tapping and sacrificing them, adding .
11. Cast Scourge of Nel Toth from your graveyard by paying and sacrificing two Saprolings.
12. When the Saprolings die, Pitiless Plunderer triggers twice, creating two Treasure tokens.
13. Repeat from step 3.

This clever loop relies on Pitiless Plunderer and Infested Thrinax turning routine sacrifices into an engine of unlimited resources. When you sacrifice Scourge of Nel Toth to Bloodflow Connoisseur, Infested Thrinax rewards the nontoken death by flooding your board with Saprolings, while Pitiless Plunderer generates the necessary Treasure. Those Treasures easily fund the black mana required to recast Scourge of Nel Toth directly from your graveyard by sacrificing two more Saprolings, feeding Bloodflow Connoisseur growing counters along the way.
