Ghave, Guru of Spores + Sadistic Glee + Utopia Mycon

Ghave, Guru of Spores

Sadistic Glee

Utopia Mycon

How it works

1. Activate Ghave's first ability by paying 1 and removing a +1/+1 counter from a creature you control, creating a 1/1 Saproling creature token.
2. Activate Utopia Mycon's second ability by sacrificing the Saproling, adding 1.
3. When the Saproling dies, Sadistic Glee triggers, putting a +1/+1 counter on the creature it is attached to.
4. Repeat.

This self-sustaining loop turns Ghave, Guru of Spores into a one-man engine by leaning entirely on the death triggers provided by Sadistic Glee. When you use Ghave to spend a counter and spawn a Saproling, you can immediately sacrifice that token to Utopia Mycon for mana to fund the next iteration. As the Saproling hits the graveyard, Sadistic Glee ensures a fresh +1/+1 counter is constantly fed back into the system to keep Ghave's ability humming along. Utopia Mycon even pulls double duty by letting you occasionally generate mana from sacrificed tokens without disrupting the core loop, making this a brilliantly tight Commander-legal win condition.
