Add a new rule called “The Strongest Spell”:

As a weekly action, a Wizard can cast the Strongest Spell by pointing their finger at a screen their choice, having their thumb raised too, and saying “Bang!” out loud; along spending an amount of Food equal to the Upkeep of a Creature plus 3 and making a blog post that is clearly for the purpose of this action. Upon doing so, that Creature is unceremoniously removed from its Wizard’s stable.

That blog post shall then be also considered a Duel, with the City Gates as battlefield, the King as its only valid Judge and the Druid as its only valid Opponent. The Druid should accept this Duel whenever possible, stating how guns aren’t real magic, with the challenger optionally scoffing back smugly with conviction that they actually are.
