Lobelia Sackville-Baggins
The design conceit is punishment aimed at a very specific moment: the instant an opponent's creature dies in combat or to removal, this Halfling flashes in and repossesses the corpse before it can be recurred, then hands you Treasure equal to whatever that creature was worth. The window is razor-thin (the card must have hit the graveyard from the battlefield that same turn), which turns Lobelia into a reactive tool that reads the board rather than a proactive threat. Two things make the effect earn its slot. First, Flash and Menace mean the body itself is not dead weight when there is no target: a 2/3 that ambushes on the crack-back and demands two blockers is a real, if modest, presence. Second, the Treasure payout scales with the exiled creature's power, so the more valuable the thing you deny, the more mana or ramp you extract from denying it, folding graveyard hate and acceleration into a single trigger. It is a rare instance of a hatebear that pays you rather than just taxing the opponent. The flavor lands the design cleanly: Lobelia was Middle-earth's most notorious appropriator of other people's belongings, and a card whose entire function is snatching a freshly fallen creature out from under its owner and pocketing the proceeds is about as faithful a mechanical portrait as a two-line trigger can manage.
