Mercenary Knight (POR-99) is a creature card from the Portal set identified as a Human Mercenary Knight. It has an enters-the-battlefield triggered cost: you must sacrifice it unless you discard a creature card, creating a hand-resource tension when played. Its 4/4 body for three total mana in black positions it as a midrange threat that demands a discard payoff or creature-heavy deck to avoid self-sacrifice.
