This clever loop hinges on a delightfully punishing interaction between Spear Spewer and Dissipation Field, turning the self-inflicted pain of the little defender into a permanent-bouncing engine. Each time Spear Spewer taps to ping your opponents (and yourself), Dissipation Field sees that permanent deal damage to you and dutifully returns it right back to your hand, freeing you up to cast it again. Meanwhile, Birgi, God of Storytelling provides the crucial red mana needed to recast the creature every single iteration, generating infinite storm and damage. While Frostcliff Siege sits quietly on the board, its presence doesn't disrupt this tightly wound mechanism, allowing the loop to execute seamlessly across a wide variety of formats from Modern to Commander.
