If you can manage to cast two spells beforehand, Twisted Fealty becomes a one-card win condition with Stella Lee that allows her to keep copying the spell in order to untap herself and drain your opponents with the Wicked Role tokens
The price of both the Chronicles and Time Spiral versions prove that the inherent value of the cards content is very low
Its a perfect 2/2 bear for 2, who has ward accompanying vigilance, reach, and trample
Origin of Metalbending Toph makes metal really flexible and Origin of Metalbending puts a +1/+1 counter on your board, because you know green decks love those counters
You can mutate it with a great reprint like Cold-Eyed Selkie for some strong commander damage, which is the decks primary threat angle
I love this card for any green-splashed Standard decks, and it has a ton of value in lots of other Constructed formats
