Firebending Student

Prowess and mana ramp usually sit in different design conversations: one belongs to a tempo shell that wants to grow a creature and swing, the other to a deck that leaps ahead on lands and rituals. Firebending Student welds them to a single stat line by making the mana an attack produces equal to the creature's power, which is exactly the number prowess is built to inflate. Cast a cheap noncreature spell before combat and the body swells; each point of that swelling converts to red mana the instant it attacks. The elegance and the constraint are one fact: prowess fades at cleanup, and the Firebending mana evaporates when combat ends. There is no swing-over-swing compounding here. The card offers a single burst locked to one attack step, and whatever mana it yields must be spent inside that window, most naturally on instant-speed pump that pushes the same swing (each pump re-triggering prowess and feeding damage back into the attack in real time). The 1/2 frame keeps the tradeoff honest: a fragile enabler that does nothing without a board and demands a hand full of cheap spells to convert one clean attack into a flood of mana and burn. What earns the design a second look is the collapse of two axes onto a single number, where the resource the swing generates and the trigger that grew the attacker are both governed by the creature's power.
