Face-down permanents enter the battlefield without revealing their normal characteristics, usually through mechanics such as morph, disguise, manifest, and cloak. This hides their identity from opponents and can make combat much harder to predict.
Ixidor, Reality Sculptor strengthens face-down creatures and can turn them face up, while Vannifar, Evolved Enigma rewards disguise and cloak. Manifest dread provides another way to put creatures onto the battlefield face down.
