Blood Funnel + Memory Crystal + Haze of Rage + Urabrask // The Great Work + Deekah, Fractal Theorist

Blood Funnel

Memory Crystal

Haze of Rage

Urabrask // The Great Work

Deekah, Fractal Theorist

How it works

1. Cast Haze of Rage with buyback by paying . Urabrask, Haze of Rage's storm ability, Blood Funnel and Deekah trigger.
2. Resolve the Urabrask trigger, adding and dealing 1 damage to an opponent.
3. Resolve the Deekah trigger, creating a creature token.
4. Resolve the Blood Funnel trigger, causing you to sacrifice the creature token.
5. Resolve the Haze of Rage trigger, creating a copy of it for each spell cast before it this turn.
6. If you created copies of Haze of Rage this way, Deekah triggers for each copy, creating that many creature tokens.
7. Resolve all Haze of Rage spells.
8. Repeat.

This loop turns a single red mana into an explosive, game-ending storm of spells by drastically slashing costs and immediately recycling your resources. Blood Funnel and Memory Crystal team up to make Haze of Rage completely free to cast with buyback, reducing its base cost and its buyback cost down to zero. As you cast and repeatedly buy back Haze of Rage, Urabrask provides the red mana and direct damage to fuel your loop, while Deekah, Fractal Theorist transforms every single cast and copy into an army of scaling Fractal tokens. Those very same tokens created by Deekah are then fed directly to Blood Funnel's sacrifice requirement to dodge its counter effect, perfectly fueling a continuous cycle of enters-the-battlefield, leaves-the-battlefield, and death triggers.
