Morsel Theft

The whole pitch of Prowl is a discount you earn through combat, and this design shows exactly what that bargain is worth. Pay full price and you have a Drain Life with the dial fixed at three: a fine but unremarkable swing of six life total. Connect first with a Rogue, though, and the cost drops to two mana and the spell staples a card draw onto the same effect, turning a vanilla life-swing into genuine card advantage that keeps your tempo intact. That conditional draw is the entire reason to run it: a black drain spell that refills its own hand is doing two jobs at the rate of one, but only on a turn where you have already committed a body to combat and gotten it through. The constraint is what makes the payoff fair, since it asks the deck to be built around connecting Rogues rather than holding the spell as reactive reach. As a window into what Prowl was trying to be, this card is unusually clear: not a free discount but a reward for an aggressive board state you had to assemble first, with the bonus tuned precisely to the deck that could meet the requirement.
