Blood Funnel

Memory Crystal

Seething Anger

Birgi, God of Storytelling // Harnfel, Horn of Bounty

Murmuring Mystic

How it works

1. Cast Seething Anger with buyback by paying . Birgi, Blood Funnel and Murmuring Mystic trigger.
2. Resolve the Birgi trigger, adding .
3. Resolve the Murmuring Mystic trigger, creating a creature token.
4. Resolve the Blood Funnel trigger, causing you to sacrifice the creature token.
5. Resolve the Seething Anger spell.
6. Repeat.

This loop turns a seemingly restrictive cost-reduction puzzle into a powerful engine by exploiting how buyback and cost modulators interact. With Blood Funnel lowering noncreature spells by {2} and Memory Crystal reducing buyback costs by {2}, Seething Anger's usual casting cost of {R}{3} is slashed down to just a single red mana. As you cast the spell over and over, Birgi, God of Storytelling fuels the loop by refunding that exact red mana while Murmuring Mystic churns out a steady supply of 1/1 Bird Illusion tokens. Those very same tokens satisfy Blood Funnel's sacrifice penalty when it tries to counter your spells, allowing the Seething Anger to safely resolve, pump your creatures, and loop right back into your hand via its buyback ability.
