Blood Funnel

Memory Crystal

Searing Touch

Sedgemoor Witch

Electro, Assaulting Battery

How it works

1. Cast Searing Touch with buyback by paying . Electro, Blood Funnel and Sedgemoor Witch trigger.
2. Resolve the Electro trigger, adding .
3. Resolve the Sedgemoor Witch trigger, creating a 1/1 Pest creature token.
4. Resolve the Blood Funnel trigger, causing you to sacrifice the Pest.
5. When the Pest dies, it triggers, causing you to gain 1 life.
6. Resolve the Searing Touch spell.
7. Repeat.

This loop turns a simple burn spell into an infinite engine by drastically discounting its cost and turning every casting into a self-sustaining cycle. Thanks to Blood Funnel, Searing Touch's noncreature cost is reduced by {2}, and Memory Crystal further reduces its buyback cost by {2}, allowing you to cast the spell over and over for just a single red mana. When you cast it, Sedgemoor Witch's magecraft ability triggers to generate a Pest token, giving Blood Funnel the creature it needs to sacrifice so the spell isn't countered. Meanwhile, Electro, Assaulting Battery generates the exact red mana you need each time you cast an instant or sorcery while also banking any unspent red mana, letting you convert the entire loop into infinite damage, lifegain, and storm count.
