This clever loop turns Searing Touch into an infinitely recastable engine of destruction by leaning heavily on cost-reduction math and token generation. Thanks to Memory Crystal reducing the buyback cost and Blood Funnel slashing the base casting cost by {2}, you can cast Searing Touch for just a single red mana. Blood Funnel normally demands a creature sacrifice to let the spell resolve, but Storm-Kiln Artist and Murmuring Mystic eagerly step in with magecraft triggers to provide a steady stream of Treasures and Bird Illusion tokens—allowing you to easily pay the sacrifice cost, refund your spent mana, and incinerate your opponents with limitless damage.
