Illithid Harvester // Plant Tadpoles (HBG-122) - Alchemy Horizons: Baldur's Gate

Ceremorphosis — When this creature enters, turn any number of target tapped nontoken creatures face down. They're 2/2 Horror creatures.

Tap X target creatures. They don't untap during their controllers' next untap steps. (Then exile this card. You may cast the creature later from exile.)
