Ulasht, the Hate Seed + Sadistic Glee + Ashnod's Altar

Ulasht, the Hate Seed

Sadistic Glee

Ashnod's Altar

How it works

1. Activate Ulasht by paying 1 and removing a +1/+1 counter from it, creating a 1/1 Saproling creature token.
2. Activate Ashnod's Altar by sacrificing the Saproling, adding CC.
3. When the Saproling dies, Sadistic Glee triggers, putting a +1/+1 counter on Ulasht.
4. Repeat.

This clever loop centers on Ulasht, the Hate Seed, which fuels its own activation by spending a +1/+1 counter to spawn a 1/1 green Saproling token. Ashnod's Altar then steps in to sacrifice that newly minted Saproling, generating two colorless mana to pay for Ulasht's ability while leaving extra mana behind. Meanwhile, Sadistic Glee watches quietly from the enchantments sideline, instantly feeding that sacrificed creature's death right back into a fresh +1/+1 counter on Ulasht to keep the cycle spinning infinitely.
