Rulings

If two Pramikons on the battlefield disagree on which direction three or more players must attack, players can't attack at all.
If no choice was made for Pramikon (perhaps because it's actually Volrath, the Shapestealer in an impressively clever disguise), its last ability has no effect.
In a multiplayer game, players may use any mutually agreeable method to determine seating order after they've chosen decks but before the game begins. If players can't agree (perhaps because Pramikon has them worried about who their nearest opponent is), players should be seated randomly.
