Soul Scourge
The life loss comes with a refund clause attached, and that tension defines the whole package. The enter-the-battlefield trigger knocks three off the target player's total, which is real pressure to pair with an evasive body. But the leave-the-battlefield trigger hands all of it back the moment the creature dies, gets bounced, or is exiled, so the three life is a loan the opponent reclaims by killing a 3/2 they were going to kill anyway. The result frames an early-era design problem: how do you give a midrange flier a relevant chunk of life-swing without printing a clean drain-and-keep effect? The answer here is to make the life loss temporary rather than permanent, which keeps the body's rate honest at the cost of making the trigger nearly irrelevant in any game that goes long. The fragile 3/2 frame matters because flying alone does not protect it: any removal spell refunds the life and removes the clock in one motion. Where it earns its keep is in the window where it connects and then sticks; if the opponent has no answer, the upfront loss plus repeated flying damage closes faster than the stat line suggests. It is a creature built around an interval the opponent largely controls, and that asymmetry (the three life stays gone only as long as they cannot interact) is the point of the printing.
