Blade of the Bloodchief + Scurry Oak + Phyrexian Altar

Blade of the Bloodchief

Scurry Oak

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing another creature, adding one mana of any color.
2. When the creature dies, Blade of the Bloodchief triggers, putting a +1/+1 counter on Scurry Oak.
3. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
4. Repeat.

This clever loop transforms a simple sacrifice cycle into an unstoppable engine by leveraging Phyrexian Altar to feed your mana pool while sending a creature to the graveyard. That death triggers Blade of the Bloodchief, which places a vital +1/+1 counter on Scurry Oak to awaken its token-generating ability. The newly birthed Squirrel token then steps up as the next sacrifice for the Altar, seamlessly sustaining the loop and yielding infinite mana, death triggers, and counters.
