Neheb, the Eternal

Most red ramp cares about creatures, treasures, or rituals that pay you mana up front and let the cost sort itself out. This rebuilds the engine around combat math instead. The second ability turns every point of life your opponents lose this turn into a postcombat red mana, which means the body and the afflict trigger are not just clocks: they are the fuel pump. Swing with a blocked attacker and afflict 3 banks three mana before damage even resolves; stack that under burn, multiplayer attacks, or a doubler like Gisela, Blade of Goldnight and the mana count balloons into something the printed text struggles to express politely. The 4/6 frame is the quiet discipline here: it is durable enough to attack into open boards and survive the block that triggers the payoff, but it produces nothing until your second main, so the mana arrives one step too late to fizzle a counterspell or hold up interaction. You are paid for damage already done, not damage you might do. That timing is the whole personality. It rewards a deck that has already committed to dealing life loss and then asks what to do with the absurd red mana surplus that commitment generates, which in practice means another haymaker, an X-spell, or a chain of burn that closes the game in a single postcombat turn.
