This brutal pairing turns Heartless Hidetsugu's symmetrical devastation into a one-sided finisher by leveraging the passive power of Warlock Class. Once Warlock Class is advanced to Level 3, damage taken earlier in the turn is treated as loss of life that repeats at the end step, turning the goblin shaman's tap ability into a lethal recursion. Because Heartless Hidetsugu halves each player's life total (rounding down) and Warlock Class immediately replicates that exact amount as additional loss of life, opponents with even or odd life totals alike are quickly driven to zero or less without you ever having to lift a finger against them twice.
