Niambi, Faithful Healer

The tutor is the whole pitch, and it points at exactly one card: Teferi, Timebender, the three-mana Planeswalker cut of Dominaria's returned hero. This is a designed pairing, not an open-ended toolbox: the search clause names a single card and nothing else, so the body's value scales entirely with whether that one Planeswalker is worth fetching. What sets the effect apart from an ordinary tutor is that it reaches the graveyard as readily as the library, so a Teferi that gets countered, milled, or discarded is not gone; the trigger pulls it back to hand the next time she enters. That recursion loop (the Planeswalker leaves play, then a flash-blink or a rebuy of Niambi retrieves it) is the strategic axis the card rewards, and it is why the two halves were built to be run together. Left to her own devices she is a modest 2/2 whose enters trigger does nothing without the named card in the deck; the design deliberately stakes her relevance on a single deckbuilding commitment rather than on flexible value. As a piece of the era's characterization, she is the healer tied to Teferi's story, and the mechanical leash between the two cards is that flavor made literal: find the wizard, keep finding him, however many times the game tries to take him off the table.
