Flavor Draft is a casual limited Magic: The Gathering Draft format where players build their opponent's card pool. It is drafted and played as normal, except for the fact that in-game flavor trumps the written text of the cards.
On most Magic cards, the mechanics mesh incredibly well with the flavor. This is not always the case, though. Even the most evocative cards face flavor issues from time to time. This is remedied by Flavor Draft.
Whenever something happens that they think doesn't make sense flavor-wise, they call over a judge (known as a Flavor Judge) to rule on whether something can happen. If the flavor judge doesn't rule that it makes flavor sense, the action or effect is stopped.
