Blood Funnel + Memory Crystal + Haze of Rage + Urabrask // The Great Work + Sedgemoor Witch

Blood Funnel

Memory Crystal

Haze of Rage

Urabrask // The Great Work

Sedgemoor Witch

How it works

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

This loop turns a simple pump spell into a devastating engine by turning its buyback cost into a self-sustaining sacrifice loop. Because Memory Crystal and Blood Funnel both reduce the costs of your spells by {2}, casting Haze of Rage with its buyback becomes entirely free, costing just the single red mana. Every time you cast it, Urabrask fuels your mana while Sedgemoor Witch provides the exact creature token needed to satisfy Blood Funnel's counter-unless-you-sacrifice tax. As the storm count climbs, Haze of Rage multiplies into an overwhelming number of copies, triggering Sedgemoor Witch repeatedly to flood the board with Pest tokens, pump your entire team, and incinerate your opponents through Urabrask's persistent damage.
