Chimney Imp

Few cards illustrate the gap between "has an ability" and "does something" as starkly as this one. The death trigger isn't removal, isn't card advantage, isn't tempo: it sets an opponent back a single draw step, and only after the Imp has already died, and only if they have a card in hand worth slowing down. By the time the trigger resolves you have spent five mana on a 1/2 flier and traded it away to make an opponent re-draw a card they were going to draw anyway. The effect is real but its value is roughly the cost of a turn-cycle of patience, paid by you, redeemed by them. It has earned a particular kind of infamy as shorthand for a creature whose rate is so far underwater that the designers seem to have priced the flavor (a chimney-dwelling imp's petty nuisance) over any combat or board reality. There is no hidden engine here and no archetype it was built to serve; the body flies, which is the only line on the card doing honest work. What it documents instead is a moment in design history before death triggers were tuned to matter, when "when this dies, mildly inconvenience someone" could be printed at five mana and shipped without a second thought.
