Impulse draw as a repeatable engine has always carried a hidden tax: the exiled card evaporates if you do not spend it before the window closes, so the ability rewards decks that can act now rather than bank resources. A tap each turn peels the top card and hands you a short lease to play it, which means the deck built around this wants a low curve and a full board of cheap threats, not a pile of expensive payoffs it cannot deploy in time. What separates the design from the many red "cast off the top" effects is the Doctor's companion tag: it is built to pair with the Doctor, converting a value-oriented partner into a red aggression engine that keeps feeding the board from exile rather than casting once and moving on. Red gets card advantage rarely and almost always on this exact leash, where the advantage is temporary and speed is the price of admission. Paired correctly, the tap stops being a trickle and becomes the throttle on how fast the deck burns through its own library, punishing hesitation and rewarding a curve that never asks you to hold anything back.
