Rulings

• 2016-09-20
  The draw step is after the upkeep step, so drawing a card as a turn-based action won't affect whether Ghirapur Orrery's second ability triggers.
• 2016-09-20
  Ghirapur Orrery's first ability is cumulative if more than one is on the battlefield.
• 2016-09-20
  Ghirapur Orrery's first ability allows a player to play an additional land during his or her main phase. Doing so follows the normal timing rules for playing lands.
• 2016-09-20
  No player may take actions in a turn before Ghirapur Orrery's second ability checks to see if it should trigger. If the player whose turn it is has any cards in hand, it won't trigger.
• 2016-09-20
  If the player has any cards in hand as Ghirapur Orrery's second ability resolves, the ability does nothing. Notably, a second Ghirapur Orrery won't have a player draw another three cards unless the player empties his or her hand after resolving the first one's trigger.
• 2016-09-20
  In a Two-Headed Giant game, Ghirapur Orrery's second ability triggers for each player on a team separately. If one player has cards in hand, it can still trigger for the other player.
