This clever loop turns the graveyard into your personal hand, fueled endlessly by the synergy between Flame Jab and Dakmor Salvage's retrace and dredge mechanics. As you repeatedly cast the red spell from your graveyard, Runaway Steam-Kin grows with +1/+1 counters to act as your mana engine, converting those casts into the red mana needed to keep going. Meanwhile, Moonveil Regent provides the crucial card-draw trigger that replaces your discarded lands with Dakmor Salvage via dredge, all while churning through your deck to fuel the loop and deal near-infinite damage.
