This explosive loop relies on repeatedly casting and copying Chain Lightning, turning your own spell into a self-sustaining engine. Every time you cast or copy the spell, Storm-Kiln Artist's magecraft ability triggers to generate extra mana in the form of Treasures, a production rate that Jolene, the Plunder Queen happily supercharges by doubling your token creation. As Chain Lightning repeatedly slams into Brash Taunter, the goblin's indestructible nature shrugs off the punishment while its triggered ability translates that incoming damage directly into a lethal stream of life loss for your opponents.
