Equivalent cards to Lonesome Unicorn (white, adventure creature that creates a Knight/Token):

• Shepherd of the Flock (white, adventure creature, returns permanent)
• Realm-Cloaked Giant (white, adventure giant, sweeper/adventure)
• Order of Midnight (black, but Adventure Knight; closest in function)

Reason: There aren’t direct white adventure knights with token creation, but these are the closest white adventure creatures.
