Tragedy Feaster

A 7/6 trampling demon for four mana that also taxes anyone trying to remove it is a rate that should not exist, and the Infusion clause is the bill that comes due. Big cheap black demons have always carried an upkeep tax in some form: Juzam Djinn drained you every turn, Phyrexian Negator fed on your permanents when it took damage, and Abyssal Persecutor forbade you from winning while it lived. This one attaches the cost to a condition rather than a clock: at the beginning of each of your end steps in which you have not gained life, you feed it a permanent. That reframes the whole build around it. Lifegain is not a value engine here; it is the off switch, a per-turn toll you pay to keep the demon from eating your own board. The tension is that the payment and the payoff pull against each other. The body wants an aggressive shell that ends games before the sacrifices pile up, but the shutoff wants incidental lifegain woven into that same curve. Ward's discard cost sharpens the trap further: the demon protects itself for cheap, so an opponent who cannot answer it early is often stuck watching you decide whether to feed it or find a lifegain source. It is the classic drawback-demon design idea, rebuilt so the drawback is a deckbuilding puzzle rather than a fixed penalty you simply absorb.
