Patron of the Moon + Golgari Rot Farm + Lotus Cobra

Patron of the Moon

Golgari Rot Farm

Lotus Cobra

How it works

1. Activate Patron of the Moon by paying 1, putting Golgari Rot Farm from your hand onto the battlefield tapped.
2. When Golgari Rot Farm enters the battlefield, it and Lotus Cobra trigger.
3. Resolve the Golgari Rot Farm trigger, returning it from the battlefield to your hand.
4. Resolve the Lotus Cobra trigger, adding 1.
5. Repeat.

This loop is a masterclass in turning a card's own drawback into a perpetual motion machine, fueled entirely by the mana generation of Lotus Cobra whenever a land arrives. By using Patron of the Moon's active ability to repeatedly cheat Golgari Rot Farm back onto the battlefield for just one generic mana, you trigger the bounce land's entry ability to return itself safely to your hand—ready to be replayed instantly. Because Golgari Rot Farm keeps bouncing itself back to your hand rather than clogging up the board, you can cycle it through the battlefield endlessly while Lotus Cobra converts each of those entries into a fresh stream of mana.
