Ghyrson Starn, Kelermorph turns any source that deals exactly 1 damage into a 3-damage ping by adding 2 more, so the deck floods the board with creatures and enchantments that repeatedly deal 1 damage whenever you cast spells or draw cards, creating a relentless stream of triggered damage. Spells that hit every opponent or every creature for 1 damage become board-clearing or life-draining events, and effects that amplify damage further, like Repercussion redirecting creature damage to players, accelerate the bleeding. The primary win conditions are Niv-Mizzet, Parun paired with Curiosity, Ophidian Eye, or Tandem Lookout, generating loops of card draws and damage triggers that close out the game in a single turn.
