Thieves' Auction

Set aside all permanents. You choose one of those cards and put it into play tapped under your control. Then your opponent chooses one and puts it into play tapped under his or her control. Repeat this process until all cards set aside this way have been chosen. (Local enchantments with no permanent to enchant remain removed from the game.)

Exile all nontoken permanents. Starting with you, each player chooses one of the exiled cards and puts it onto the battlefield tapped under their control. Repeat this process until all cards exiled this way have been chosen.

The magical dust clouds Mercadian mages use to traverse the plane generate storms that devastate the surrounding terrain. But as long as the storms don't touch the mountain, the nobles simply don't care.
