Equivalent cards include:
1. Innocent Traveler – Original card.
2. Heir of Falkenrath – Black human that transforms if a condition is met (though needs discarding).
3. Graveyard Glutton – Black creature with a transformation trigger (requires exile from graveyard).
4. Westvale Abbey (transforms into Ormendahl, Profane Prince) – A black card that requires sacrificing creatures to transform.

None are exact, but these share the black color, transformation, and/or condition-based transform triggers related to creatures.
