While Fate Unraveler didn’t see much competitive Standard play, it was a creature that deck brewers had a lot of fun with, especially in Mono-Black. Fate Unraveler’s ability had a nice synergy with Master of the Feast, an extremely popular creature at the time. Being a 5/5 flyer for only 3 mana meant that the Master of the Feast had a drawback: each opponent draws a card at the beginning of your upkeep. Having the Fate Unraveler deal 1 damage each time this happened at least made your opponent feel pain for it.
Outside of Standard, Fate Unraveler has become a favorite of many Commander players . In multiplayer Commander games, you can benefit from a great many life loss triggers. Being an Enchantment, Fate Unraveler has found homes in popular Commander decks such as Daxos the Returned, Mogis, God of Slaughter, and Yidris, Maelstrom Wanderer. But the best deck for Fate Unraveler has proven to be Nekusar, the Mindrazer. With all of the cards that Nekusar decks force opponents to draw, Fate Unraveler helps complement his ability to hurt your opponents for each card they draw.
Fate Unraveler also has nice synergy with the draw spell Damnable Pact, which is played in many Nekusar decks. Damnable Pact can force an opponent to draw a great many cards, as it’s an X spell. It also makes the player lose X life, an ability make even more deadly with the Unraveler’s ability.
Over the years, Fate Unraveler has been used in many casual decks, especially in Commander. Her popularity in Commander even prompted Wizards of the Coast to reprint her in one of the Commander 2015 decks, Call the Spirits. While the Fate Unraveler isn’t going to be worth much in price, she’s a valuable card for any Commander player’s Magic collection.
