Blood Funnel + Memory Crystal + Judith, Carnage Connoisseur + Urabrask // The Great Work + Seething Anger

Blood Funnel

Memory Crystal

Judith, Carnage Connoisseur

Urabrask // The Great Work

Seething Anger

How it works

1. Cast Seething Anger with buyback by paying . Urabrask, Blood Funnel and Judith trigger.
2. Resolve the Urabrask trigger, adding and dealing 1 damage to any target.
3. Resolve the Judith trigger, creating a 2/2 Imp creature token.
4. Resolve the Blood Funnel trigger, causing you to sacrifice the Imp.
5. When the Imp dies, it triggers, dealing 2 damage to each opponent.
6. Resolve the Seething Anger spell.
7. Repeat.

This cunning loop centers on casting Seething Anger repeatedly by leveraging its buyback cost, which is completely offset by Memory Crystal reducing buyback costs by {2} and Blood Funnel making noncreature spells cost {2} less to cast. Whenever you cast the spell, Blood Funnel's drawback demands a sacrifice, but Judith, Carnage Connoisseur and Urabrask // The Great Work trigger simultaneously to handily provide ammunition by generating a 2/2 Imp token and netting you {R} plus a point of damage. Sacrificing that very same Imp to satisfy Blood Funnel triggers its death ability to deal 2 damage to each opponent, looping the entire process into an infinite storm of damage, triggers, and creature sacrifices.
