This vicious loop relies on a closed-circuit synergy between damage, lifegain, and card draw that effortlessly closes out a game. Once you draw a single card to kick things off, Niv-Mizzet, the Firemind fires off a point of damage to an opponent, which immediately triggers Bloodthirsty Conqueror to make you gain that much life. That sudden burst of life activation forces Marina Vendrell's Grimoire to draw you a card, seamlessly feeding right back into Niv-Mizzet, the Firemind's damage ping. Meanwhile, Marina Vendrell's Grimoire also protects you from losing the game due to having zero life, ensuring your engine runs safely until every opponent is reduced to ash.
