Memory Crystal + Sculpting Steel + Searing Touch + Electro, Assaulting Battery

Memory Crystal

Sculpting Steel

Searing Touch

Electro, Assaulting Battery

How it works

1. Cast Searing Touch with buyback by paying .
2. Electro triggers, adding .
3. Resolve Searing Touch, dealing 1 damage to any target and returning Searing Touch to your hand.
4. Repeat.

This clever loop turns Searing Touch into a relentless, recurring engine by leveraging the passive cost-reduction of Memory Crystal alongside the clever artifact cloning of Sculpting Steel. Because Memory Crystal slashes the buyback cost of Searing Touch down to just two generic mana—and since Searing Touch originally costs one red mana—its total casting cost becomes a mere $\{1\}\{R\}$. The final piece of the puzzle is Electro, Assaulting Battery, whose static ability ensures you don't lose unspent red mana as phases end while its triggered ability refunds an $\{R\}$ every time you cast an instant or sorcery. Together, Electro, Assaulting Battery and Memory Crystal drop the net cost of casting Searing Touch below the mana it generates, allowing you to repeatedly fire off the spell and loop it back to your hand for infinite damage, storm count, and magecraft triggers.
