Creature — Unicorn
3 / 3
Vigilance
Sorcery — Adventure
Create a 2/2 white Knight creature token with vigilance. (Then exile this card. You may cast the creature later from exile.)
When casting a spell as an Adventure, use the alternative characteristics and ignore all of the card's normal characteristics. The spell's color, mana cost, mana value, and so on are determined by only those alternative characteristics. If the spell leaves the stack, it immediately resumes using its normal characteristics.
