Primal Prayers + Enduring Renewal + Bloodflow Connoisseur

Primal Prayers

Enduring Renewal

Bloodflow Connoisseur

How it works

1. Cast the creature that causes you to get energy counter(s) when it enters the battlefield by paying E due to Primal Prayers.
2. When the creature enters the battlefield, it triggers, causing you to get at least E.
3. Activate Bloodflow Connoisseur by sacrificing the creature.
4. When the creature dies, Enduring Renewal triggers, returning the creature from your graveyard to your hand.
5. Resolve the Bloodflow Connoisseur ability, putting a +1/+1 counter on it.
6. Repeat.

This clever loop turns cheap creatures into a relentless cycle of sacrifice and rebirth, powered entirely by Primal Prayers allowing you to cast low-mana-value creatures using energy instead of mana. Once the creature is on the field, Bloodflow Connoisseur steps in as the sacrifice outlet, steadily growing larger with every iteration by converting your creatures into +1/+1 counters. Meanwhile, Enduring Renewal ensures that nothing stays in the graveyard for long, immediately bouncing the fallen creature right back to your hand so you can recast it for energy.
