The Wizardly Barge is a rare Legendary Kindred Artifact — Wizard Vehicle card from Unknown Event (UNK), collector number RZ03r.
Other Wizards you control get +1/+1. Whenever the Wizardly Barge attacks, create a token that's a copy of a random tournament-legal Wizard creature. (I'd suggest looking them all up online and choosing one at random.) Crew 1
