Blood Funnel + Memory Crystal + Judith, Carnage Connoisseur + Searing Touch + Electro, Assaulting Battery

Blood Funnel

Memory Crystal

Judith, Carnage Connoisseur

Searing Touch

Electro, Assaulting Battery

How it works

1. Cast Searing Touch with buyback by paying . Electro, Blood Funnel and Judith trigger.
2. Resolve the Electro trigger, adding .
3. Resolve the Judith trigger, creating a creature token.
4. Resolve the Blood Funnel trigger, causing you to sacrifice the creature token.
5. Resolve the Searing Touch spell.
6. Repeat.

This loop turns Searing Touch into a self-sustaining engine by exploiting massive cost reductions. Memory Crystal shaves {2} off the buyback cost, while Blood Funnel knocks another {2} off the spell's total cost, allowing you to cast Searing Touch for a mere single red mana. Whenever you cast that instant or sorcery, Electro, Assaulting Battery generates floating red mana to offset the cost while hoarding your unspent mana through phases, and Judith, Carnage Connoisseur obligingly provides a 2/2 red Imp creature token. That token is immediately fed to Blood Funnel's sacrifice requirement when its counter trigger resolves, fueling a continuous loop of damage and triggers.
