If your deck is aggressive this is not a great tool and if you have few low value recursion targets this will also under perform although will at least remain playable
It can also be useful in Commander to clear a full stack since you can choose different targets for each copy, potentially letting you stop multiple players
In addition to making disguised creatures, Vannifar, Evolved Enigma can buff your whole board of manifested creatures, an effect that plays really well with Orochi Soul-Reaver or Glitch Interpreter since your creatures are harder to block
That Shadow deck in particular took full advantage of Reanimates other big edge: resurrecting opposing creatures under your control is surprisingly useful, especially if you arent playing an all-in Reanimator strategy and are less likely to have a target in your own yard
As a result, whenever an MTG set comes out with some good new rats, this card shoots up in price
This deck transforms defenders into conquerors, turning their immense toughness into devastating power
